Chisquared Distribution Function Explained

Description

Step by step demonstration of the chisquared distribution calculus.

Usage

explain.chisquared(x,y)

Arguments

x

Should be a vector.

y

Should be a vector.

Details

To calculate the chisquared distribution, the user should give two vectors of numbers. The result is a sum of the squares of k independent standard normal random variables. We can saw the chisquared distribution formule in the chisquared_ help document.

Value

Numeric result and the process of this calculus explained.

Note

A vector is created by c(), like c(1,2,3,4,5) creates a vector with the numbers: 1,2,3,4,5
