fixed effect model with industry dummy variables

[karamat khan]

hi all, im new to Stata I will appreciate ur answer for solving my prob.
Im using three types of variables, 185 companies 11 industries over period 10 years, to see the impact of firm characteristics(independent variables) and industry impact(indep) on capital structure(dep) while controlling for corporate governance variables(control variables). Now my prob is mostly studies suggest fixed effect model and when I do "xtset id year" and run ylist xlist industrydummy clist, hausman test also suggest fixed effect model, but by doing fixed effect Stata omit results for industry impact and control variables, Now if I set panel only "year" then I get result for all variables but im not sure tht result are right or wrong becz in setting "xtset year" now the model suggest random effect instead of fixed effect and the rho is very small like .0007 (which I don't understand what it means. and this is also against the previous research in the area which suggest fixed effect model, my question are
1) how should I set panel for achieving my objective mentioned in first line
2) how can I get industry impact and clist impact using fixed effect model
3) what is the interpretation of low roh is it good or bad ?
4) I should use ylist xlist indlist clist for getting hausman test or only main variables like ylist xlist or ylist xlist indlist? and then decide which model is effective ? below image shows how I organized my data

Karamat:
1) you should -xtset id year-. -xtset year- is not correct (and 3) the low R is immaterial, since your data are ill-xtset-);
2) you can add -i.industry- and -i.clist- as predictors. However, under -fe- specification, time-invariant variable are cancelled out and you do not get any coefficient about them;
4) a given regerssion model is correct as long as it gives a fair and true view of the data generating process.
As an aside, please do not post screenshots. See the FAQ on how share with the list what you typed and what Stata gave you back via CODE delimiters and/or an example/excerpt of your data via -dataex-. Thanks.

Respected Carlo Lazzaro sir im really thankful for ur kind answer and I will be careful next time for posting screenshots,, as u said in ur reply fe specification will not give coefficient about time invariant variables but I have seen many studies where they reported industry effect using dummy variables with fixed effect specification and that's reason im confused if its not possible using fixed effect specification then how they reported?

[Carlo Lazzaro]

Karamat:
if the studies you mention actually use -fe- specification, coefficient of -i.industry- can be reported only for those firms (if any) that changes industry as time goes by.
As an aside, please call me Carlo, as all on (and many more off) the list do. Thanks.
