Inverse cumulative normal distribution
Inverse cumulative normal distribution calculates a value that represents the
location within a normal distribution for a specific cumulative probability.
Specify the probability and use this formula to obtain the integration interval.

Example To calculate inverse cumulative normal distribution for a
specific parameter value
For this example, we will determine inverse cumulative normal
distribution when probability value = 0.691462,
σ
= 2 and
