Dear All:
I am writing a simple linear regression. I have the following code:
reg y i.fourthq##i.type i.bank1
There are 26 banks with 14 valid observations each. The fourth and type are the dummy variables.
after i run the above code, i was expecting 26 bank regression results. But, in reality, it gives me 24 bank coefficients for the banks and two of them missing.
For the one missing bank in the regression, i saw the following note on the stata:
***************************
> 369033
usbank | .4819995 2.115589 0.23 0.820 -3.679604 4.
> 643603
wellsfargod | 0 (omitted)
|
_cons | 1.895873 1.696801 1.12 0.265 -1.441928 5.
*****************************
I checked a lot and there are no mistakes in the data or the code. I do not think there is collinearity with other variables too.
I even independently run regressions for the two banks exclusively, but stata even does not show regression results too.
Can someone help me explain why does the stata drop the regression results for the specific bank category?.
Thanks.
