bgnbd.PlotTransactionRateHeterogeneity {BTYD} | R Documentation |
Plots and returns the estimated gamma distribution of lambda (customers' propensities to purchase).
bgnbd.PlotTransactionRateHeterogeneity(params, lim = NULL)
params |
BG/NBD parameters - a vector with r, alpha, a, and b, in that order. r and alpha are unobserved parameters for the NBD transaction process. a and b are unobserved parameters for the Beta geometric dropout process. |
lim |
upper-bound of the x-axis. A number is chosen by the function if none is provided. |
This returns the distribution of each customer's Poisson parameter, which determines the rate at which each customer buys.
Distribution of customers' propensities to purchase.
