Hello, may I ask a question for my regression: I did the Hausman test and the result was 0.000 -> so i am going to use the Fixed Effects Regression. After I used the Peusch-Pagan Test it showed me a result of 1.000 which means that I should or can use the POLS regression. Should i continue with the FE or the POLS?
You must run 02 selection processes separately for 02 dependent variables; in each process, run the hausman test for selecting the right model of each dependent variable. Good luck!
may I ask that in this case , there are two control variables gdp growth and size , there are all classified as independent variable in 10:05? isn't there a menu to choose them for control variable or they are treated same as other independent variables. thank you professor if I want to add moderate variable , where can I add it in the menu?
Control variables are treated same as other independent variables. I'm very sorry that the panel data analysis has not yet addressed the moderating effect. I'm also trying to find how to add a moderating variable, but I haven't found a way yet.
@@HKTStata I found that you can run the moderate effect by multiplying with the dependent variable ,that is the only way ,but I am curious that if you are a professor why you still don't now this , thank you for your reply
Testing moderating effects by multiplying two independent variables is a simple and theoretical method. This often requires accompanying robust tests for the moderating effect (e.g., the PROCESS macro developed by A.F. Hayes for SPSS; however, not suitable for panel data analysis). Therefore, this multiplication method may not convince "rigorous" reviewer. I emphasize "rigorous" ones; thus, you can still try using this method.
@@HKTStata thanks I got it, but when I saw the published paper, it moderating effect was run by multiplying independent variable and dependent variable ,not two independent variables , thank you for your reply ,All in all,I still gain a lot from your videos ,which save my thesis.
multiplying independent variable and dependent variable is wrong. Please see doi.org/10.1037/0022-3514.51.6.1173 & ademos.people.uic.edu/Chapter14.html
Hi thank you for the video which is very helpful. One comment on the first hausman test result to be sure: wouldn't it be that we "reject" the null hypothesis (H0: random effect is a preferred model) as the p-value is 0.000, and accept the H1: fixed effect is a preferred model? The video says that the hausman test allows us to "accept" the null hypothesis and choose to use fixed effects.
Thanks for your comment. The correct interpretation must be "the hausman test allows us to reject the null hypothesis and choose to use fixed effects". Random effects (RE) is preferred under the null hypothesis due to higher efficiency, while under the alternative Fixed effects (FE) is at least as consistent and thus preferred. If the p-value is small (less than 0.05), reject the null hypothesis.

In hausman test p value came 0 means fixed effect model is appropriate but in xttest0 p value came 1 means pooled is appropriate. So which on is appropriate for this analysis??? Please can you explain
You should see the figure 1 in our article doi.org/10.3390/su11174569 You can use only the hausman test for your decision. You can see also czcams.com/video/AxFVb75QSf4/video.html
The hausman test is for choosing between random or fixed effect model. The xttest0 is for choosing between pooled OLS or random effect model. If the hausman test is significant (p < 0.05), it means fixed effect model is appropriate; then you can ignore the xttest0 according to the figure 1 in our article doi.org/10.3390/su11174569
In my opinion, multiple OLS and pooled OLS are the same; let's see the regression equation at the end of phantran.net/different-regression-models-with-panel-data-fixed-effects-random-effects-and-pooled-ols/
dots in Stata output mean missing values. The standard errors for those two coefficients could not be computed; presumably there is a problem of near-collinearity in the regressors (assuming this is regression output).

Please reply me, is xttest0 in choosing model and xttest0 in check heteroskedasticity for RE model the same? REM is appropriate model for my data. First I check xttest0 to choose between RE and POLS then I use hausman to choose between RE and FE. Now I want to check heteroskedasticity for RE. What should I do?
To check heteroskedasticity for RE, you should use 2 following commands: xtgls Y X1 ...Xn, panels(hetero) xtreghet Y X1 ... Xn, id(ID) it(Year) model(xtmln) mfx(lin) diag lmhet If heteroskedasticity, run: xtreg Y X1 ... Xn, robust re Good luck :)
You must assure that fixed and random regression have stored before run haussman test. Plz retry by respecting the following steps: 1. Performing fixed-effects regression by using command xtreg with option fe, 2. and save the fixed-effects estimates 3. Performing random-effects regression by using command xtreg with option re, 4. and save the random-effects estimates 5. the Hausman test with sigamore option
Thanks for your great work!...AT the end, yoo explain the meaning of "rho", and the slide says "97.466% of the variance is due to differences across panels"...Did you want to say "entities" instead of "panels"?...Thanks again!
As you know robust model may fix the heteroskedasticity problem and also Pooled OLS fixes the serial correlation problem. Which model is preferable if both (heteroskedasticity and serial correlation) tests are failed?
For Pooled OLS, you just test the heteroskedasticity, if the test failed, you should use robust option. You do not need the serial correlation test, this is only for panel data models such fixed and random effects ones; Pooled OLS ignores the time effect.
@@HKTStata Thanks for your prompt response. But I wanna comprehend the issues around my problem. My data has both heteroskedasticity and autocorrelation problems. Which model is feasible for this type of problem sir?
