{{alias}}( x, k, λ )
Evaluates the probability density function (PDF) for a Weibull distribution
with shape parameter `k` and scale parameter `λ` at a value `x`.
If provided `NaN` as any argument, the function returns `NaN`.
If provided a nonpositive value for `λ` or `k`, the function returns `NaN`.
Parameters
----------
x: number
Input value.
k: number
Shape parameter.
λ: number
Scale parameter.
Returns
-------
out: number
Evaluated PDF.
Examples
--------
> var y = {{alias}}( 2.0, 1.0, 0.5 )
~0.037
> y = {{alias}}( 0.1, 1.0, 1.0 )
~0.905
> y = {{alias}}( -1.0, 4.0, 2.0 )
0.0
> y = {{alias}}( NaN, 0.6, 1.0 )
NaN
> y = {{alias}}( 0.0, NaN, 1.0 )
NaN
> y = {{alias}}( 0.0, 0.0, NaN )
NaN
> y = {{alias}}( 2.0, 0.0, -1.0 )
NaN
{{alias}}.factory( k, λ )
Returns a function for evaluating the probability density function (PDF) of

Scale parameter.
Returns
-------
pdf: Function
Probability density function (PDF).
Examples
--------
> var myPDF = {{alias}}.factory( 7.0, 6.0 );
> var y = myPDF( 7.0 )
~0.155
