- naginterfaces.library.stat.pdf_normal_vector(ilog, x, xmu, xstd)[source]¶
pdf_normal_vector
returns a number of values of the probability density function (PDF), or its logarithm, for the Normal (Gaussian) distributions.For full information please refer to the NAG Library document for g01kq

- Notes
The Normal distribution with mean , variance ; has probability density function (PDF)
The input arrays to this function are designed to allow maximum flexibility in the supply of vector arguments by re-using elements of any arrays that are shorter than the total number of evaluations required. See the G01 Introduction for further information.
