Command Syntax
x value, σ value, µ value
Definition of Terms
x : data value
σ : standard deviation ( σ > 0)
µ :mean
Specifying σ = 1 and µ = 0 produces standard normal distribution.
Input Example:
NormPD 3,1,0
Calculation Result Output
p : normal probability density
Normal Distribution Probability
Command: NormCD 䡺
Description: This command calculates the probability of normal distribution data falling
between a and b.
a : lower boundary (Lower)
b : upper boundary (Upper)
Command Syntax
Lower value, Upper value, σ value, µ value
