Call me insane, but after a lot of this stuff started clicking, I’m having a good time reviewing. Is it bad that I’m happy I’m staying in all weekend, saving money, and furthering my intelligence/education? Stress is starting to creep up on me, but for now, I’m not hating L2. Though that could easily change on 6/6.
LIES!!!
seriously if you were right next to me i’d punch you right now.
That pic of you was a lie, this is not. I’m not working, so this is what I do all day everyday. The opportunity cost for me is the hours of daytime TV I’m missing. L2>Daytime TV It’s kinda fun once you get it.
Insane.
It’s not fun when you only have 1 day in a year to show you get it. 
I hate you. FML. Actually, since you’re not working, do you mind if I send you an email about a model I’m working on?
Well, sure. I can tell you I won’t be too much help though. Email is quantjockmba at g m a i l My modeling is pretty poor. Swap and I (and whoever else wants in) are going to kill w@ll st prp (Ch.ad blocks out the name of this service due to fetchxl). So after killing L2, we’re going to kill wsp. I’m not trying to be that guy, some of the tougher stuff I finally get. I’m sure all of you can relate to the positive self actualization when you finally understood the Arch Model, First Differencing, 3 errors compare/contrast, etc. I am feeling better about my progress after learning some stuff that threw me for a loop each time I went over it.
I hear ya man, in a weird way, i look forward to my weekend study martathons.
Sent. No worries, dude. You’re way ahead of me. I know ARCH stands for Auto Regressive Conditional Heteroskedasticity and gets tested using B.P., but that’s about it. I’ve woken up with soiled trousers (not really) after having nightmares about unit roots.
Got it. I looked at it and will give you some insight. Take it lightly as I have close to zero experience modeling other than w@llstreetprep. Few notes I took. RMSE - Lower is better. Square root of MSE, one wants low amount of errors. This is to compare the predictive accuracy of two separate autoregressive models. This is tested with in sample data. Random Walk - Unit root - b1 = 1 which makes the mean reverting level undefined. b0/1-b1 and you can’t divide by zero. Random walk, like a drunk dude stumbling after bar close, past stumbles are no indication of future stumbles. He won’t revert to a straight line when ordered to on a dwi stop either. With no mean reverting level, time series is nonstationary. Unit Root Random Walk’s cure is First Differencing. New dependent variable is difference of x1 and x2. Other In AR Model coefficient must be <1 If coefficient = 1 or is greater, you get a random walk and model does not work. Use this AR Model rule to test seasonality. If seasonality is present, one needs to incorporate lags and use the AR2 Model. After including lagged variables, check the T stats to be sure they are LESS THAN 2 which means they are not significant. Nonstationarity - Critical assumption of time series is violated. Test- Plot data, run AR model and test correlations, Perform Dickey Fuller test BEFORE running AR model. Check for Unit Roots Both covariance stationary - OKAY Only independent or dependent variable covariance stationary - NOT OKAY Neither time series is covariance stationary - Probably OK, check cointegration Cointegration - two time series are related to macro variables that follow same trend and relationship is constant. These were my rough notes I took late last night. Hopefully it helps clear up some of the convoluted quant talk that is in the curriculum and notes.

Though that could easily > change on 6/6. I love this stuff too. I wouldn’t be doing it if I dreaded studying for this program. All of the material is specifically catered to the career path I am focusing on. How else can you get out of bed in the morning at 5:30 am to put in 2 hours of study before work if you don’t absolutely live for this shit??

I think we all have a love/hate relationship with this stuff. No one in their right mind should be spending 900-ish hours studying for a charter if they hate the material, but I could definitely do without all of the stress that comes with it!!! (Though, admittedly, I am enjoying the material itself more the second time around - except quant and derivatives, that is. I could go the rest of my life without looking at another time series regression!!)
ditch, Good man… at least you have peace of mind and only have to prepare for this… I just got to know that I won’t get any leave for this exam…maximum could be one or two days… that is almost close to nothing… It may also happen that I will keep working till Friday evening and go to exam on Saturday… 
Till now I was thinking, I might be able to take a week off…
In response to how “fun” this is I will also reply. Like ditch, I am unemployed, so this is like my job. I typically get about eight hours a day in. Here are the things I would be doing if not studying: Playing golf Playing soccer Cycling Playing tennis Skiing in Tahoe (late season, squaw is still open Being in Europe Being in Southest Asia Golfing and playing tennis in the previously mentioned locations Watching the giants play baseball Going to the beech Looking for a summer job before school starts In summary, there are many things that I would prefer to do that are relatively much more fun than this. Instead, I am going to take on Treynor-Black and crush that b!tch. Then I am going to happy hour followed by studying all day tomorrow also. I am going a little crazy.
I would rather be doing all of those things too, but since I’m unemployed, I’m bound to reading at the library since $$$ is tight.
I hate all you unemployed people, you will raise the score…
Hopefully
I shared the thought about love/hate relationship with the study material but this week I’ve been a little low in motivation to study/review but hope to reverse it this weekend…
