Dear Richard and all of you who replied:

I now better understand my error of interpretation (more related to stats than to Stata !!!). The p-value of the coefficient 2.02 is 0.056 (i.e., not significant at the 0.05 level).

The number of df is: 3 (model) + 22 (residual) = 25 (total).
Do you know where I could find the critical value corresponding to each df, and particularly this one?

Best regards

Hervé

di invttail(df,0.5*alpha)

will give you the (absolute value of the) critical value for a test of Beta= 0 at the alpha % level for the specified df.

hence,

di invttail(25,0.025)

gives the critical value at the 5% level for 25 df (which happens to be 2.0595386)

Best,
Antoine.





Best,
Antoine.
