Hi Professor Kling, thanks so much for your videos. How does the model you show account for the panel nature of the data? Or does it? Can we include an interaction term using xtreg to account for the panel nature of the data (instead of regress as you have demonstrated, which would be an SOLS/POLS model as you've explained in your video Introduction to Panel Data)?

@YUNIKARN 22 күн бұрын

A fixed effects model allows (only) a shift in the intercept but the slope coefficients are constant (fixed). Interaction effects go further by permitting changes in slope coefficients. They can be combined with fixed effects - but I would not recommend using xtreg, fe (the default) as you might like more control over the dummies used in fixed effects models. I tend to prefer xi: reg y x i.code and add the cross-sectional dummies and maybe additional shifts in slope coefficients.

Ph.D. In quantitative finance: My topic to be Machine learning algorithms for risk management in trading activities. The main objective is to develop a prototype framework for pricing and risk management using machine learning algorithms. I have been given 2 years to complete this PhD project from a hedge fund company, and they are the ones financing it. After my graduation, I will be able to continue to work there. The main objective is to be able to do something I stand 100% behind and love doing, not outside of my interest. This PhD project is being funded by a hedge fund company, which has given me two years to complete the project. I'll be able to keep working there once I graduate. I genuinely enjoy doing this, and I spend the majority of my days on this project, even though I haven't started yet. What do you think the response from any university I apply to would be? As professional experience. By the way, I'm from the Netherlands.

@YUNIKARN 3 ай бұрын

Two years is short. Most PhD programmes will require three years. So you will need to think about self-funding one year or finding alternative arrangements (write-up periods etc.). I worked at Utrecht University. The Dutch system is quite different from the UK as most PhD students have a teaching position. Do you want to try the Dutch market or UK/US? You need a good fit with a potential supervisor. Good luck!

Amazing outlook. I have been inquisitive over time regarding specifically unemployment. As an 22 year old finance professional, I firsthand observe the incredibly heavy mismatch between potential service sector jobseekers (more so for higher paying multinationals) and the relatively static job growth. The last generation has seen a significant shift towards the service and that's something that isn't stopping any time soon. Are we potentially moving towards a high unemployment universal basic income type economy or is the worldwide job market going to adjust these professionals.

Hi, I have 4 dependent variables, when I run the hausman test for each one of them, 2 of them validate the random effect model, and the 2 others validate the fe model. Now which one to choose since I'm doing a multivariate regression? And on top of that, some of my dummy variables (usefull ones) are ommitted under fixed effect, but I really need to use them.

@YUNIKARN 5 ай бұрын

I did a video on "Why does Stata drop my variables?", which will be published on Monday 1st April 2024 - April Fool's Day Special. Link: kzbin.info/www/bejne/eZirpph4ecZ4pLc If you have four dependent variables, it suggests that you will have four separate models to explain them. Of course, you can have FE or RE as these models are separate. If you do not know which one is actually dependent, then you need to explore causality (or causal order if you have a time dimension). May the Force be with you!

When I run the VIF command after having run the Corr command STATA tells me "not appropriate after regress, nocons; use option uncentered to get uncentered VIFs". What does that mean? And also, the Hausman Test tells me to use the fixed effect model, but when I use it, STATA omits my dummy variables in the result. "Omitted because of collinearity" What can I do now?

@YUNIKARN 6 ай бұрын

You can do your on VIF. Just regress all explanatory variable one by one on the set of all other explanatory variables. Obtain the R squared. The VIF is then 1/(1-R squared). Or add a constant to your regression model. The implementation of the VIF command is a bit odd in Stata. Second problem: the fixed effects dummies seem to explain other dummies in the model. Stata drops these to avoid collinearity (the inverse of the data matrix does not exist as the matrix does not have full rank). Check the definitions of your dummies
