PerformCohortRetentionTests: Compares treatment to control on retention rate for given...

In rvladimiro/dafR: Data Analysis Framework in R

Description

This function receives a summarised dataset and compares the retention rates for each avaliable test group against the control. The dataset should have the columns containing the following information: acquisition_date | activity_date | retention_day | group | active_users The names of the columns can differ

This function should also receive a character vector that identifies the name of the control group, as well as the names of the columns containing metrics of interest

This function uses the prop.test function to perform a simple chi^2 on the proportion of users who return N days after their acquisition. If no retention days are provided, then the function will perform tests for each one avaliable.

Returns p-value for two-tailed test and statistics for each comparison to control

Arguments

dataset	The summarised dataset
retentionDays	An integer vector containing the retention days to test. If not provided will test all avaliable non-zero retention days
controlName	The name which identifies the control group in the dataset
groupColumn	The name of the column that contains the group identification
retentionDaysColumn	The name of the column that contains the retention day identification
usersColumn	The name of the column that contains the sum of users for each combination of acquisition and activity dates
acquisitionColumn	The name of the column that contains the dates of acquisition
...	Additional arguments to pass on to prop.test function

Value

A dataframe containing p-value for two-tailed test, boundaries for confidence intervals, for each tested retentention day and treatment group
