Exercise

Visualizing influences on purchase probability

Let's try plotting and interpreting the purchasing behavior model from the last lesson. You'll step through several iterations of plots of log_mod2, moving from raw plots on the fitting scale towards plots on the response scale with more natural interpretations.

The model (log_mod2) from the previous exercise is available in your workspace.

Instructions 1/4

XP

1
Plot all partial effects of log_mod2 on the log-odds scale. Put all plots on a single page.
2
Convert the plots to the probability scale using the trans argument.
3
Convert the plots to probability centered on the intercept with the shift argument.
4
Add intercept-related uncertainty to the plots using the seWithMean argument.
