"at regular intervals" problem

[noobplus]

ive a notepad of 'n' lines, each value in an array xArray[n]
now I've to find out "kurtosis" for every 5 values of 'n'
(for example, kurtosis(first 5 values), kurtosis(next 5 values), etc)
*kurtosis is a formula which can be written in an expression..

double zz=((TotalLineCount*(TotalLineCount+1))/((TotalLineCount-1)*(TotalLineCount-2)*(TotalLineCount-3))*(kurtbr))-((3*(TotalLineCount-1)*(TotalLineCount-1))/ (TotalLineCount-2)*(TotalLineCount-3));

*kurtbr is already been calculated by an expression. and now,
how do we create the loop to do it every five values.
ive tried this:

for(int j=0;j<(n);j=j+5)
  {
     for(int k=j+0;k<j+5;k++)
       {
          double[] zz = /**the formula mentioned earlier**/ z1;
          
        }
   }

is there a simpler technique?
