*0 only if <math>observed ij = expected ij</math> for each <math>i</math> and <math>j</math>.
*0 only if <math>observed ij = expected ij</math> for each <math>i</math> and <math>j</math>.
*CHITEST uses the <math>\chi^2</math> distribution with the number of Degrees of Freedom df.
*CHITEST uses the <math>\chi^2</math> distribution with the number of Degrees of Freedom df.
*where <math>df=(r-1)(c-1),r>1</math> and <math>c>1</math>.
*If <math>r=1</math> and <math>c>1</math>, then <math>df = c-1</math> or if <math>r>1</math> and <math>c=1</math>, then <math>df = r-1</math>.
If <math>r = c = 1</math> then this function will give the error result
If <math>r = c = 1</math> then this function will give the error result
