$$\frac {\sum_{i=1}^N (x_i-u)/N}{p^4}$$

Is it only top part of the fraction including the N or just whatever is in the parenthesis. I'm making a code that includes this equation and I need to put it in a loop so that is why I am asking. Also pretend the p and u are numbers they already declares I just did not know how to put it on here so they are placeholders.

  • That's poor notation, but I'd guess it means $\cfrac {\frac{1}{N}\sum_{i=1}^N (x_i-u)}{p^4} = \cfrac {\frac{1}{N}\left(\sum_{i=1}^N x_i\right)-u}{p^4},$. – dxiv Mar 17 '17 at 06:16
  • Yea sorry about that it was given to me like that so I didnt know if N was part of the summation equation. – Rafael Mar 17 '17 at 06:19
