meangaitd: Mean of the GAITD Combo Density

Description

Returns the mean of a 1- or 2-parameter GAITD combo probability mass function.

Usage

meangaitd(theta.p, fam = c("pois", "log", "zeta"),
    a.mix = NULL, i.mix = NULL, d.mix = NULL,
    a.mlm = NULL, i.mlm = NULL, d.mlm = NULL,
    truncate = NULL, max.support = Inf,
    pobs.mix = 0, pobs.mlm = 0,
    pstr.mix = 0, pstr.mlm = 0,
    pdip.mix = 0, pdip.mlm = 0, byrow.aid = FALSE,
    theta.a = theta.p, theta.i = theta.p, theta.d = theta.p, ...)

Value

The mean.

Details

This function returns the mean of the PMF of the GAITD combo model. Many of its arguments are the same as dgaitdplot. More functionality may be added in the future, such as returning the variance.

Examples

i.mix <- seq(0, 15, by = 5)
lambda.p <- 10
meangaitd(lambda.p, a.mix = i.mix + 1, i.mix = i.mix,
          max.support = 17, pobs.mix = 0.1, pstr.mix = 0.1)
