Command Syntax
x value, σ value, ∝ value
Definition of Terms
x : data value
σ: standard deviation (σ > 0) ∝ : mean
Specifying σ = 1 and ∝ = 0 produces standard normal distribution.
Input Example:
NormPD 3,1,0
Calculation Result Output
p : normal probability density

Command: NormCD
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
