The Chi Square Distributions

The equation for the chi square distribution is

                                                

 

The above equation conforms to the general form of the Euler's gamma function

 

                                                        

 

The constant a equals

 

                                                        

 

the constant b equals

 

                                                          

 

the constant c equals .5 and the constant d equals 2.

 

For example, for 10 degrees of freedom

 

                                                           

 

b equals 4, c equals .5 and d equals 2.
