Usage

Cumulative distribution function (CDF)

Returns the cumulative distribution function for the given mean and sigma, evaluated at x.

NormalDistribution(mean: -0.21, sigma: 1.7).cdf(x: -0.73);
// Result: 0.3798471227404693

Note:

• Returns null if sigma is zero or negative.

Probability density function (PDF)

Returns the probability density function for the given mean and sigma, evaluated at x.

NormalDistribution(mean: -0.21, sigma: 1.7).pdf(x: -0.73);
// Result: 0.22394634407779582

Note:

• Returns null if sigma is zero or negative.
