Function Normal(Mean, Deviation)

Normal

The function Normal draws a random value from a normal distribution.

Normal(
    Mean,       ! (optional) numerical expression
    Deviation   ! (optional) numerical expression
    )

Arguments

Mean

A scalar numerical expression.

Deviation

A scalar numerical expression \(> 0\).

Return Value

The function Normal returns a random value drawn from a normal distribution with mean Mean and standard deviation Deviation.

Graph

A graph with:

• a histogram for 1.000 experiments of drawing from distribution Normal(0,10), and

• the DistributionDensity for Normal(0,10)

Example

The code:

option seed := 1234 ;
_p_draw := Normal( 0, 10 )  ;
_p_pointDensity := DistributionDensity( Normal( 0, 10 ), 3 );

block where listing_number_precision := 6 ;
        display _p_draw, _p_pointDensity ;
endblock ;

will produce

_p_draw := 6.124772 ;
_p_pointDensity := 0.038139 ;

in the listing file.
