Zero-augmented Gamma Probability Density Function
dzag(x, mu, phi, pi, log = FALSE)
vector of (non-negative) values.
mean/s (non-negative) for the gamma distribution.
dispersion parameter for the gamma distribution.
vector of (real lying in [0, 1]) zero-inflation parameters.
logical; if TRUE, probabilities, p, are given as log(p).
The (log) probability mass at x, given mu, phi, and pi.
