logistic: Standard Logistic Function

In XiaoqiLu/ziclust: What the Package Does (One Line, Title Case)

Description

Equivalent to stats::plogis() with default arguments.

Usage

logistic(x)

Arguments

x	a numeric input

Details

The standard logistic function is defined as

p(x) = \frac{1}{1 + e^{-x}}.

We decided to write our own implementation instead of using the C/C++ powered stats::plogis() after benchmarking performance.

Value

a (0, 1)-ranged output of the same size as x

Examples

logistic(0)
