- Normal[Mean μ, Standard Deviation σ, x ]
- Creates probability density function (pdf) of normal distribution.
- Normal[Mean μ, Standard Deviation σ, x, Boolean Cumulative]
- If Cumulative is true, creates cumulative density function of normal distribution, otherwise creates pdf of normal distribution.
- Normal[Mean μ, Standard Deviation σ, Variable Value x]
- Calculates the function Φ((x – μ) / σ) where Φ is the cumulative density function for N(0,1).
- Note: Returns the probability for a given x-coordinate's value (or area under the normal distribution curve to the left of the given x-coordinate).
CAS Syntaxes
In CAS View only following syntax is supported:
- Normal[Mean μ, Standard Deviation σ, Variable Value x]
- Calculates the function Φ((x – μ) / σ) where Φ is the cumulative density function for N(0,1).
