Probabilities::UniformDPDF Function

Probabilities Namespace

Overload List

#SignatureDescription
1double UniformDPDF(int x, int N);Discrete uniform probability mass function (PMF).
2void UniformDPDF(TMtxVecInt *X, int N, TDenseMtxVec *Res);Discrete uniform distribution PDF (vectorized).

Overload 1: double UniformDPDF(int x, int N);

Discrete uniform probability mass function (PMF).

#NameTypeDescription
1xintFunction domain, integer on the closed interval [1,N].
2NintUpper bound of the support; N must be a positive integer (N>=1).

Returns: the discrete uniform probability mass function (PMF) at x using parameter N. Returns NAN when N<1; 0 outside the support.

Remarks:

The discrete uniform distribution puts equal weight 1/N on the integers 1,2,...,N:

PMF(x| N)=1/N, x=1,2,...,N

Domain: x in {1,...,N}, N >= 1. For N<1 the result is NaN; for x outside [1,N][1,N] the result is 0.

Overload 2: void UniformDPDF(TMtxVecInt *X, int N, TDenseMtxVec *Res);

Discrete uniform distribution PDF (vectorized).

#NameTypeDescription
1XTMtxVecInt *Defines distribution domain, vector or matrix with integer values on closed interval [1,N].
2NintDistribution parameter, positive integer.
3ResTDenseMtxVec *After calculation stores the PDF calculated from X and N. Length and Complex properties of Res are adjusted automatically to match Length and Complex properties of X.
