Parameters:

zarray_like

The quantiles of the combined probability density function (pdf).

pdf_1Callable

The pdf of the first random variate.

pdf_2Callable

The pdf of the second random variate.

loc_1float

The loc parameter of the first pdf.

scale_1float

The scale parameter of the first pdf.

loc_2float

The loc parameter of the second pdf.

scale_2float

The scale parameter of the second pdf.

operatorstr

The operator that defines the new random variate given by Z = X Y. Currently supported operators are {"+", "*"}.

nint

The precision of the numerical integration. The integration uses 2 ** n intervals to evaluate the integral.

Returns:

outndarray

The value of the pdf at the given z quantiles.
