Chi-Squared data distribution

Implements a chi-squared distribution. The classes Pearson2xk and ZSquared are subclasses, used in two different situations. Pearson2xK is used when testing k groups for homogeneity in response rates. The null hypothesis is r₁=...=r_k, and the alternative is that there exists a pair of groups with differing rates. ZSquared implements the square of a normally distributed random variable with mean \(\mu\) and standard deviation \(\sigma^2\).

Usage

ChiSquared(df)

# S4 method for class 'ChiSquared'
quantile(x, probs, n, theta, ...)

simulate(object, nsim, n, theta, seed = NULL, ...)

Arguments

df

further optional arguments
