Logistic regression with two explanatory variables
Logistic regression also supports multiple explanatory variables. To include multiple explanatory variables in logistic regression models, the syntax is the same as for linear regressions.
Here you'll fit a model of churn status with both of the explanatory variables from the dataset: the length of customer relationship and the recency of purchase, and their interaction.
churn is available.
