Computes the pdf of the generalized gamma distribution
Usage
dgengammad(x, b = 1, d = 1, k = 1)
Arguments
x
scale or vector of positive values at which the pdf needs to be computed
b
the value of b parameter, must be positive
d
the value of d parameter, must be positive
k
the value of k parameter, must be positive
Value
An object of the same length as x, giving the pdf values computed at x
Note
If incorrect values are input for x or the model parameters then NaNs will be returned as the output.
This function uses the R contributed package VGAM.
