Get PMF of a discretized Gamma distribution

Source: R/utils_dists.R
get_discrete_gamma.Rd

This function accepts different parameterizations to specify a discretized Gamma distribution.

Usage

get_discrete_gamma(
  gamma_shape,
  gamma_rate,
  gamma_scale,
  gamma_mean,
  gamma_sd,
  gamma_cv,
  maxX = NULL,
  include_zero = TRUE,
  print_params = FALSE
)

Arguments

gamma_shape

Shape parameter of the Gamma distribution.

gamma_rate

Rate parameter of the Gamma distribution.

gamma_scale

Scale parameter of the Gamma distribution. Can be specified instead of the rate. Only has an effect if the rate is not specified.

gamma_mean

Alternative parameterization: Mean of the Gamma distribution.

gamma_sd

Alternative parameterization: Standard deviation of the Gamma distribution.

gamma_cv

Alternative parameterization: Coefficient of variation of the Gamma distribution.

maxX

Right truncation point. All probability mass beyond maxX will be assigned to maxX. If NULL (default), this is automatically chosen such that the last bin has less than 0.5% of the probability mass.

include_zero

Should the distribution explicitly cover X=0, or should X=1 include the probability mass for X=0 too?

print_params

Should the shape and rate parameters be printed?

Value

A numeric vector representing the PMF of the discretized Gamma distribution.
