Decimal Factorials

I believe that one would compute a decimal factorial like the example below:

4.75! = 4.75 * 3.75 * 2.75 * 1.75 * 0.75 = 64.29

Someone please correct me if I am wrong.

I don't understand how you got a non-integer for the k value. That may be
where the problem lies.

After that, I would compare the probability of x to the empirical frequency
in the
numerator.

I wonder if you could help. I'm having a mental block on decimal
factorials.

Specifically, I was doing a Pearson's Chi-square problem with a fitted
negative binomial. The K parameter was 1.76. So, how do I go about
solving for different values of x:

( x+k-1)
( ) p^k q^x ?
( x )

Thanks!
