zPdf
default double zPdf(double z) Returns the probability density function for \(z\). The default distribution is the standard normal distribution. Implementations may override these methods to use different distributions.- Parameters:
z- adouble, the value of \(\epsilon/\sigma\)- Returns:
- a
double, the value of the probability density function atz
