Module Squantiles.Chi_deux (.ml)

module Chi_deux: sig .. end

This module can be used to get the quantiles of a Chi-2 law. Quantiles were taken from http://www.agro-montpellier.fr/cnam-lr/statnet/tables.htm.

val probabilities : probability list

val string_of_probability : probability -> string

val quantile_of_freedom_degree : ?p:probability -> int -> float

quantile_of_freedom_degree n returns the quantile for the given freedrom degree n.
Raises Invalid_degree if n < 1 or n > 100

p : can be used to specify the probability. Default is `p0_95.

exception Out_of_table of string

val probability_of_quantile : int -> float -> probability

probability_of_quantile degree q returns the probability corresponding to the given degree (<=100) and the given quantile.
Raises Out_of_table if degree > 100 or the given q is greater than the quantile associated to the greatest probability.
