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.

- Extract and print confidence intervals from the fitted model using
`.conf_int()`

function.
