Calculating the posterior difference

The posterior proportion_clicks for the video and text ad has been put into a single posterior data frame. The reason for [1:4000] is because these proportion_clickss are not necessarily of the same length, which they need to be when put into a data frame.

Now it's time to calculate the posterior probability distribution over what the difference in proportion of clicks might be between the video ad and the text ad.

  • Add a new column posterior$prop_diff that should be the posterior difference between video_prop and text_prop (that is, video_prop minus text_prop).
  • Plot posterior$prop_diff as a histogram using hist().
