double LogarithmicPDF(int x, double p);
Logarithmic (log-series) probability mass function (PMF).
| # | Name | Type | Description |
|---|---|---|---|
| 1 | x | int | Function domain, positive integer (x>=1). |
| 2 | p | double | Distribution parameter, real value on the open interval (0,1). |
Returns: the logarithmic-series probability mass function (PMF) at x using parameter p. Returns NAN when p is outside (0,1).
Remarks:
Computes the logarithmic-series PMF:
PMF(x| p)=(-1)/(ln(1-p)) p^x/x, x=1,2,3,...
Domain: x >= 1, p in (0,1). For p <= 0 or p >= 1 the result is NaN.
