I am using statsmodels to perform a robust linear regression on some data I have. I wanted to understand whether the slope of my regression is significantly different from 0. In scipy I due this by looking at the p-value.

In statsmodels, is the same null hypothesis being tested? I can get the pvalue as returned by RLMResult.pvalues but I couldn't find the documentation indicating what is being tested.

    Yes, tvalues and pvalues in model results are for the hypothesis that the parameter is zero with the alternative that it is not zero. Commented Jan 15 at 16:29
