Exercise

Confidence intervals

Continuing from the previous exercise you will now asses the uncertainty of the coefficients by computing the confidence intervals.

Recall formulas for confidence intervals discussed in the video:

95% confidence intervals for the parameter \(\beta\) $$ \hat\beta\pm1.96*SE $$
95% confidence intervals for odds $$ exp(\hat\beta\pm1.96*SE) $$

The model crab_GLM and crab dataset are loaded in the workspace.
