Computes pdf of the skewed symmetric model.
1 |
x |
scalar or vector of values to compute the pdf. |
spec1 |
a character string specifying the parent distribution g(x) (for example, "norm" if the parent distribution corresponds to the normal). |
arg1 |
list of arguments/parameters of the parent distribution g(x). |
spec2 |
a character string specifying the parent distribution H(x) (for example, "logis" if the parent distribution corresponds to the logistic). |
arg2 |
list of arguments/parameters of the parent distribution H(x). |
log |
logical; if |
The pdf of skewed symmetric model has a general form of:
f(x) = 2h(x)G(x), \quad -∞ < x < ∞
where h(x) and G(x) are the pdf and cdf of parent distributions, respectively.
An object of the same length as x
, giving the pdf values computed at x
