Statistics: binoinv

### Function Reference: `binoinv`

statistics: x = binoinv (p, n, ps)

Inverse of the Binomial cumulative distribution function (iCDF).

For each element of p, compute the quantile (the inverse of the CDF) of the binomial distribution with parameters n and ps, where n is the number of trials and ps is the probability of success. The size of x is the common size of p, n, and ps. A scalar input functions as a constant matrix of the same size as the other inputs.

Further information about the binomial distribution can be found at https://en.wikipedia.org/wiki/Binomial_distribution

### Example: 1

     ## Plot various iCDFs from the binomial distribution
     p = 0.001:0.001:0.999;
     x1 = binoinv (p, 20, 0.5);
     x2 = binoinv (p, 20, 0.7);
     x3 = binoinv (p, 40, 0.5);
     plot (p, x1, "-b", p, x2, "-g", p, x3, "-r")
     grid on
     legend ({"n = 20, ps = 0.5", "n = 20, ps = 0.7", ...
              "n = 40, ps = 0.5"}, "location", "southeast")
