hello,

please can anyone help me out. Am a new user of R program. Am having problem with this code below, not getting the expected results.

  1. Each m, the cumulative sum should be 1.000 but the 2nd and 3rd m returned 2.000 and 3.000 instead of 1.000.
  2. to get the LCL(m) and UCL(m) for each m base on these instructions if out.cum > 0.025 then LCL(m)= y-1 if out.cum >0.975 then ucl(m)= y-1 how do I code these instructions into this code.

thanks

g=g-lgamma(y+z)-lgamma(m-y+z)-lgamma(x[h]+a)-lgamma(n[h]+b-x[h])- lgamma(n[h]+m+a+b)
