As title suggest: Is it possible to have confidence intervals crossing 0 but p = 0.042?

This happened to me in glm model with gamma family and link identity. The conf. intervals were generated by tidy function in R.

How should I interpret it? Or is my model wrong?


The intervals from tidy functions seems to be based on likelihood ratio. However when I compute the Wald's CI the the values now doesn't cross 0. So is tidy function using different aproache towards CI and p value?

  • $\begingroup$ Yes, this sounds like the libraries have different methods of calculating the critical value: Wald vs likelihood ratio. $\endgroup$ – Dave Mar 15 at 13:04
