chi-squared

Characteristic functions for the chi-squared distribution.

Example

var chi = require('chi-squared')
chi.pdf(0.5, 1) // 0.4393912894677223
chi.pdf(2.3, 1.4) // 0.11695769277348175
chi.cdf(2, 2) // 0.6321204474030797

Methods

chi.pdf(x, k)

Compute the probability density function for the parameter x under k degrees of freedom.

chi.cdf(x, k)

Compute the cumulative density function. same parameters as above.
