inverse
Searches starting at the value start until the CDF > p "start" must be the smallest possible value for the range of the CDF as an integer. This requirement is NOT checked
Each value is incremented by 1. Thus, the range of possible values for the CDF is assumed to be {start, start + 1, start + 2, etc.}
Return
the found inverse of the CDF found for p
Parameters
df
a reference to the discrete distribution
p
the probability to evaluate, must be (0,1)
start
the initial starting search position
