Uplift barplot for categorical variables

Computes the observed uplift per category and creates a barplot.

UpliftPerCat(data, treat, outcome, x, ...)

Arguments

• data: a data frame containing the treatment, the outcome and the variable of interest.
• treat: name of a binary (numeric) vector representing the treatment assignment (coded as 0/1).
• outcome: name of a binary response (numeric) vector (coded as 0/1).
• x: name of the explanatory variable of interest.
