Dear BIOMCH readers,
While programming some evaluation sofware I came up with a problem
concerning the use of a cumulative probabilities table.
This is the problem:
To determine the percentile of a normal distribution you have to use a
specific table, the cumulative probabilities table. When plotting this
table as a graph you get a specific curve. The problem is that I cannot
find the formula for this curve (Using such formula makes programming a
lot easier).
I found the cumulative probability function for a continuous uniform
random variable:
y=(x-a)/(b-a) where a
