RSM predicted ROC-rating pdf for diseased cases

`RSM_pdfD(z, mu, lambda, nu, lesDistr)`

## Arguments

- z
The z-vector at which to evaluate the pdf.

- mu
The scalar RSM mu parameter.

- lambda
The scalar RSM lambda parameter.

- nu
The scalar RSM nu parameter.

- lesDistr
The lesion distribution 1D vector.

## Value

pdf, density function for diseased cases
