pgammaDif: True CDF for difference in means \bar{x} - \bar{y}

In bdsegal/gammaDist: Distribution functions and MLE for gamma random variables

Description

This function computes the true CDF for the difference in means \bar{x} - \bar{y} of gamma random variables under the null of equality in distributions. CDF derived by Klar (2015).

Usage

pgammaDif(q, nx, ny, alpha, lambda)

Arguments

q	scalar or vector of quantiles
nx	sample size of first group
ny	samle size of second group
alpha	common parameter value
lambda	common parameter value

Examples

nx <- 60
ny <- 60
alpha <- 1
lambda <- 4
q <- seq(-0.2, 0.2, 0.001)
plot(q, pgammaDif(q = q, nx, ny, alpha, lambda),
     type = "l", ylab = "F(q)")
