u Inverse Cumulative Normal Distribution
Inverse cumulative normal distribution calculates a value that represents the location within a
normal distribution for a specific cumulative probability.
f (x)dx = p
−∞
∫
f (x)dx = p
+∞
∫
f (x)dx = p
∫
Specify the probability and use this formula to obtain the integration interval.
