pdf

Normal.pdf(X)

Probability density function (PDF).

The PDF for the Normal distribution is:

\[f(x | \mu, \sigma) = \frac{1}{\sigma \sqrt{2\pi}} \exp\left( -\frac{(x - \mu)^2}{2\sigma^2} \right)\]

where \(\mu\) is the mean (loc) and \(\sigma\) is the standard deviation (scale).

Parameters:

X (ArrayLike) – The input data points at which to evaluate the PDF.

Returns:

The PDF values corresponding to each point in X.

Return type:

NDArray[np.float64]
