bgbb.PlotTransactionRateHeterogeneity {BTYD}

BG/BB Plot Transaction Rate Heterogeneity

Description

Plots and returns the estimated beta distribution of P (customers' propensities to purchase).

Usage

bgbb.PlotTransactionRateHeterogeneity(params)

Arguments

params

BG/BB parameters - a vector with alpha, beta, gamma, and delta, in that order. Alpha and beta are unobserved parameters for the beta-Bernoulli transaction process. Gamma and delta are unobserved parameters for the beta-geometric dropout process.

Details

This returns the distribution of each customer's Bernoulli parameter, which determines the level of their purchasing (using the BG/BB assumption that purchasing on the individual level can be modeled with a Bernoulli distribution).

Value

Distribution of customers' propensities to purchase.

Examples

params <- c(1.2, 0.75, 0.66, 2.78)
bgbb.PlotTransactionRateHeterogeneity(params)
params <- c(0.2, 1.5, 3.2, 6)
bgbb.PlotTransactionRateHeterogeneity(params)
