Hello to all Gretl users, i need help regarding to panel regression that i m running on
the data of 49 companies over 5 years.. disclosure score have been assigned to each
company is my dependent variable and i m seeing relation of this with diffrent variable
like assets, debt to eqity ratio, working capital etc....
I have run a random effect model without dummies... following is the result of
regression..
: Random-effects (GLS), using 245 observations
Included 49 cross-sectional units
Time-series length = 5
Dependent variable: Disclosurescore

'Within' variance = 60.0887
'Between' variance = 146.644
theta used for quasi-demeaning = 0.713727
Breusch-Pagan test -
Null hypothesis: Variance of the unit-specific error = 0
Asymptotic test statistic: Chi-square(1) = 193.78
with p-value = 4.75747e-044
Hausman test -
Null hypothesis: GLS estimates are consistent
Asymptotic test statistic: Chi-square(7) = 11.5898
with p-value = 0.114882
now i dont knw that whether i have to use interpret these beta coefficients as any other
variable or else & whether to use dummy variable or not...
I m also attaching with ths mail my data file in gretl..
Plz anyone help ..
Thanks in advance
