CADF_to_nth_purchase | CADF_to_nth_purchase
CADF_to_nth_purchase_allrows | CADF_to_nth_purchase_allrows inputs CADF data and the desired purchase number that you want to count the nth result of.
ca_SRM | ca_SRM
ca_SRM_time_varying | Time varying Simple retention model Estimates retention rate using logistic regression and the simple regression model Mostly used for contractual models where there are clear opportunities for cancellation. Could be used in non-contractional situations although the cancellation opportunities should be defined. Not recommended for use with services that consumers use rotating-door style. Use the migration model there.
ca_to_ps_matrix | CADF to purchase string Extracts purchase strings from the CADF and formats as a R matrix.
create.purchase.string | Function called during Customer$new() (the Customer R6 class) to create purchase string for the customer.
create.recency.string | create_recency_string
Customer | R6 Class representing a customer. Otherwise known as the CADF.
