flopscope.stats.laplace.pdf

flopscope.stats.laplace.pdf(x, loc=0, scale=1)[flopscope source]

Evaluate the probability density function.

Parameters

x:array_like: Points at which to evaluate the density.
loc:float, optional: Location parameter of the distribution. Defaults to 0.
scale:float, optional: Scale parameter of the distribution. Defaults to 1.

Returns

:FlopscopeArray: Probability density evaluated elementwise at x.

Notes

Equivalent to scipy.stats.laplace.pdf(x, loc, scale). FLOP cost: 22 * numel(x) (composite: |x-loc|(3) + exp(-z)(17) + /(2*scale)(2), FMA=2, weight 1.0).

system_message

<string>:1: (WARNING/2) Inline substitution_reference start-string without end-string.

Examples

>>> import flopscope.numpy as fnp
>>> import flopscope as flops
>>> x = flops.array([-1.0, 0.0, 1.0])
>>> flops.round(flops.stats.laplace.pdf(x), 3)
array([0.184, 0.5  , 0.184])
