You do know that Argyle is the seat of clan Campbell in Scotland, yes?
Very good point, if we start with an uninformed prior that any rating from 1 to 5 stars is equally likely (so the average is 3), then seeing 4.2 star rating based on 300 reviews provides new information so that we can do Bayesian updating. For simplicity I assume that people would either rate as 1 star (bad) or 5 stars (good), but one can relax this assumption later. So therefore if you see rating R based on N reviews, that implies p=N(R-1)/4 positive reviews (5 star) and q=N(5-R)/4 negative reviews (1 star). Assuming we started with an uninformed prior (e.g. 1 star and 5 star equally likely), then the posterior distribution is beta(p+1,q+1) which is approximately normal with mean p/(p+q) and variance pq/((p+q)^2*(p+q+1)). Substituting our expressions for p and q above, we get that the normal distribution has mean of m=(N*(R-1))/(4*(N+2)) and variance of var=((R-1)*(5-R))/(16*(N+1)).
Now if we observe two sets of ratings as above, R1 based on N1 reviews and R2 based on N2 reviews, we can calculate two sets of parameters (mean and variance) for the corresponding normal distributions: m1=(N1*(R1-1))/(4*(N1+2)) and m2=(N2*(R2-1))/(4*(N2+2)), then var1=((R1-1)*(5-R1))/(16*(N1+1)) and var2=((R2-1)*(5-R2))/(16*(N2+1)) where X1~N(m1,v1) and X2~N(m2,v2).
So what is the probability that rating R1 is better than rating R2? That is the same as the probability that X1 is bigger than X2, e.g. P(X1>X2). We have that P(X1>X2)=P(X1-X2>0). But (X1-X2)~N(m=m1-m2, var=var1+var2) e.g. the difference of two independent normal distributions is also normal with mean equal to the difference of means and variance equal to sum of the variances. We can standardize X1-X2: Z=((X1-X2)-m)/sqrt(var) where Z is now standard normal, Z~N(0,1). Then P(X1>X2)=P(X1-X2>0)=P(Z>-m/sqrt(var))=1-NORM.S.DIST(-m/sqrt(var)) and we can use Excel to calculate the cumulative standard normal evaluated at the parameter -m/sqrt(var).
So we get that there is 52% chance that 4.2 rating based on 300 reviews is better than 4.8 rating based on only 10 reviews. I hope that’s what you guys are doing rather than eyeballing the ratings and the corresponding number of reviews, since intuition can be misleading.
Quite a lengthy analysis for the fact that if you read the qualitative remarks of the 4.8’s … they could be all very dashing for a place that just opened.
But, Matt Likes Analysis, so he’s probably loving this.
agree that it probably make sense to improve the analysis by considering a time-weighted average rating RT=[r_1(t_1)*t1+r_2(t_2)*t_2+…+r_n(t_n)*t_n]/T where r_i(t_i) is an individual rating by some reviewer at time t_i since the opening of the establishment, and T is the time since the opening through now (so that t_i<=T for all i) and a similarly time-weighted average of the number of reviews N_T=[t_1+t_2+…+t_n]/T. Comparing time-weighted average pairs [R_T,N_T] would put more emphasis on recent ratings while still relying on the Bayesian averaging technique from above which factors in the number of reviewers. good extension.
Michelin guide or hacksaw.
Wow. I bet those mad math skills get Möbius a ton of a$$.
I bet a 250-lb tax cpa from podunktown, TX knows a lot about getting a ton of a$$!
Not.
just kidding greenie, you mah boy. Don’t be hating on mad math though. Do you see me randomly dissing irs regs in your presence? Nah, I show respect.
^haha yo is ur name a reference to starcraft 2?
btw i skimmed your passage it was too long. wtf are you putting formulas for. just read the long reviews. use filters. and find the truth
let me give you guys as an example. when i research say a club, i type key words like grind. cover. free. chicks. ratchet. hoes. parking. rap
https://www.yelp.com/biz/club-dv8-hollywood?q=grind
I had fun, maybe because I had pregamed before walking in. The music was cool until the end when they started playing SUPER gangsta rap…LOTS OF CREEPS THOUGH! that has got to be the biggest flop of the night is all the weirdo old guys lurking around. If your a girl your going to have guys trying to grind on you CONSTANTLY and be ready to push them off!! When i was outside smoking a cigarette these 3 older guys were trying to talk to me and my friend us being alittle tipsy we were being nice and keeping conversation when they started asking us if we’d do porn we were over it and went back in to dance. By the time the club was done and there was a big crowd walking out i realized i forgot to get my parking thing validated so i ran back in by myself and as i was walking out one of the guys me and my friend blew off earlier (the porn guy) was right behind me and looked at me really weird so i just kept walking and all of a sudden i feel a big ass hand grip my ass and practically pick me up by it. It was absolutely infuriating and disgusting i turned around and punched him in the face and cussed up a storm and he just laughed and gave his friend a high five…it was right next to security so i turned to the guard and said “did you see that?!” and all the security did was laugh…FUCK THAT!!! GROSS!! WARNING DO NOT PARK IN THE PARKING LOT!!! my car got broken into right under a camera and alot of shit was stolen and my car was a mess when i tried telling the security we had to wait 2 hours before anyone helped us (by that time it was 4am!!) and all they did was take pictures of the damage and tell us to call on tuesday!! i called on tuesday and they said there was nothing they could do without a supina or whatever and a bunch of bullshit! TERRIBLE TERRIBLE TERRIBLE!

best yelp review ever:
I don’t even know where to begin with this nightclub. It’s in a great location regarding parking and the bouncers are nice but that’s where all the positivity ends. We only came here because it was my friend’s birthday and she’s been here a few times. My fiance and I are a bit older but tagged along anyway. ** Clientele I’m going to assume that because it was an 18+ club and in a touristy area that they were allowing everyone in. Wearing flip-flops, jean shorts, and a graphic tee? Head on in! The girl-to-guy ratio was severely imbalanced leaving the poor girls being pounced on like a pack of hyenasstalking their prey. A few times I caught the guys flock over to a group of girls and start groping her. Completely disgusting and disrespectful. Not only that but the guys here don’t care if you came with your boyfriend or already dancing with another guy. They’ll just butt right in and push whoever you were dancing with away. One guy actually shoved both me and my fiance. My fiance shoved him back and instead of shoving my fiance again he decided to shove me. I pushed him, got in his face, and told him to stop fucking pushing me. He slinked away after realizing I was serious. The kids that go here really need to adjust their attitudes or they’ll be quickly checked. Also, about 95% of the people that go here are Mexican. Nothing wrong with that - just stating the facts. ** Bar + Drinks I asked for a gin and tonic and the dumb bartender handed me a Sprite with maybe a teaspoon of gin. Nope, sorry, I know my alcohol and I know when you’re giving me bullshit. The drink was $12. I paid $12 for Sprite in a glass. I let it slide and chalked it up to the bad choice of nightclubs. Don’t order drinks here - you’ll be ripped off. ** Music + DJ One of the only highlights of the night was the music. They played a lot of hip-hop and Top 40 hits so at least we danced. Sort of. The dance floor was insanely packed and because some of the princesses couldn’t handle their watered-down liquor there was liquid everywhere. I almost busted my ass just two-stepping in place. ** Bouncers + Location The bouncers were nice and do their job … on the outside. On the inside you just see them walk around aimlessly like they hate their jobs. I would too. The location is great because it’s in a popular area and because there is ample parking. They supposedly validate so don’t forget to validate your parking ticket! OVERALL: I would not go back. It may be that I am used to more exclusive clubs where the clientele and drinks are held to a higher standard. It may be because I don’t want to get molested or watch other people get molested. I only recommend this place if you have just turned 18 and want to get your dance on. I paid $15 cover fee and the $12 shitty drink. In the end, I paid $27 to sit on the couch with my fiance and people watch.
Do I Yelp? Bro I’m Yelp Elite. #dykwia
Yelp is worse for sushi restaurants in the non metro areas IMO. People rate based on the number of cream cheese and fried rolls. Yelp is good for almost everything but sushi in my experience with a large enough sample size, Chinese included.
youre certainly not talking about me in this post.
“Yelp is good for almost everything but sushi in my experience with a large enough sample size, Chinese included.”
It’s more accurate to say that it reflects the opinions of the population that is being sampled, and measures what is defined to be “good” based on local tastes. For instance, even though I eat at “good” sushi restaurants in NY, I’m not a sushi expert from Japan. So, a restaurant that I would rate highly might be snubbed by someone with different or more informed tastes. My opinion is based on my experience eating sushi in the US.
With Chinese restaurants, it is perhaps also more accurate to say that the opinions of non-US Asians differ from the consensus of most US locals. So when I say that US reviewers are “wrong” when rating Chinese restaurants, it is more accurate to say that their expectation is just not consistent with mine.
I agree. My point is that in most places, it is easier to find “good” Chinese food than it is sushi with a suitable sample size. This does not mean that all Chinese restaurants at 4 stars will be authentic, but it’s normally easy to separate takeout places from good sources.
I define good as the average expectation of those who have experience with the authentic cuisine of some sort. And I understand the noise this distinction adds to the conversation.
But if anyone has a super refined taste, then it’s likely not the rating that will be helpful. For me, pictures are often more useful for sushi places than the reviews.
As Gordon Ramsay says, never take pictures of your food.
I think pictures are misleading and unreliable.
How is seeing exactly what will show up on your plate unreliable? Are you suggesting vision conveys no useful information at all for food?
where im going tonight with the vegas crew to discuss itinerary
https://www.yelp.com/biz/gyu-kaku-japanese-bbq-torrance?q=happy%20hour
HAPPY HOUR, HAPPY HOUR, HAPPY HOUR!! Came here for a late dinner specifically wanting happy hour food! 99cent beer? $1.50 Sapporo? $5 hot sake? 50% off appetizers?! Slashed meat prices? Yes, please! We ordered: -FRIED EDAMAME STICKS ($2.98): DELICIOUS and highly recommended. Comes with spicy mayo sauce -Garlic shrimp ($4.95) -FILET MIGNON ($5.95) (WINNER…so tender and juicy) -NY Steak Miso ($5.95) -Spicy pork ($3.95) -Bistro Harami ($4.95) -Brown rice ($2.95) -Sapporo There’s two dipping sauces that’s regular and semi-spicy.

After the 2010 buffet at Circus Circus, I no longer trust Vegas discount food…
i agree that i am probably loving this.
