gammamix(pi, shape, scale, shift = rep(0, length(pi)))
Arguments
- pi
A vector of mixture proportions.
- shape
A vector of shape parameters.
- scale
A vector of scale parameters.
- shift
A vector of shift parameters.
Value
An object of class gammamix (a list with elements
pi, shape, scale, and shift, described above).
