Chi-Square Probability Calculator

Creates the integral and inverse integral for the Chi-Square(df) distribution. Plots of the probability density function and cumulative distribution function can also be requested.

Chi-square

Element Name Description
Inverse Creates the inverse of the integral; specify a desired p-value (e.g., significance level) to compute the critical variate value for the respective distribution.
1 - Cumulative p Set this option to True to compute the (critical) variate value for the specified distribution based on a 1-cumulative-p value, or the 1-cumulative-p value based on a specified (critical) variate value.
Plots density function Plots the probability density function.
Plots distribution function Plots the distribution function.
Chi-Square value Specifies the (critical) Chi-Square value for the computations.
p-value Specifies p-value for computations.
Parameter df Specifies the value of parameter df: Degrees of freedom.
