logistic

Logistic regression models provide information way beyond a p-value. Using the {palmerpenguins} dataset, I review the relationship between the logistic and the logit functions, and how to interpret the coefficients of a logistic regression model, capitalising on marginal effects.

ggplot

The outputs of polynomial regression can be difficult to interpret. I generated some animated plots to see how model predictions change across different combinations of coefficients for 1st, 2nd, and 3rd degree polynomials.
