{{alias}}( x, p )
Evaluates the probability mass function (PMF) for a Bernoulli distribution
with success probability `p` at a value `x`.
If provided `NaN` as any argument, the function returns `NaN`.
If `p < 0` or `p > 1`, the function returns `NaN`.
Parameters
----------
x: number
Input value.
p: number
Success probability.
Returns
-------
out: number
Evaluated PMF.
Examples
--------
> var y = {{alias}}( 1.0, 0.3 )
0.3
> y = {{alias}}( 0.0, 0.7 )
0.3
> y = {{alias}}( -1.0, 0.5 )
0.0
> y = {{alias}}( 0.0, NaN )
NaN
> y = {{alias}}( NaN, 0.5 )
NaN
// Invalid success probability:
> y = {{alias}}( 0.0, 1.5 )
NaN
{{alias}}.factory( p )
Returns a function for evaluating the probability mass function (PMF) of a
Bernoulli distribution with success probability `p`.
Parameters
----------
p: number
Success probability.
Returns
-------
pmf: Function
Probability mass function (PMF).
Examples
--------
> var mypmf = {{alias}}.factory( 0.5 );
> var y = mypmf( 1.0 )
0.5
> y = mypmf( 0.0 )
0.5
