pdfNormal

Syntax

pdfNormal(mean, stdev, X)

Details

Calculate the probability density of the specified normal distribution at X.

Its functionality and usage are the same as scipy.stats.norm.pdf.

Parameters

mean is a numeric scalar representing the mean of the normal distribution.

stdev is a numeric scalar representing the standard deviation of the normal distribution.

X is a numeric scalar or vector representing the points at which to compute the probability density.

Returns

A DOUBLE scalar or vector indicating the probability density of the specified normal distribution at X.

Examples

Calculate the probability density value of the standard normal distribution at X=1:
pdfNormal(mean=0, stdev=1, X=1)
// output: 0.24197072451914337

Calculate the probability density values of a normal distribution with mean 1 and variance 1.5 at X=1, 2, 3:

pdfNormal(mean=1, stdev=1.5, X=[1,2,3])
// output: [0.265961520267622,0.212965337014901,0.109340049783996]
