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
Aruike

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)
