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

  • 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.
