Logistic distribution functions

Compute density (mlx_dlogis), cumulative distribution (mlx_plogis), and quantile (mlx_qlogis) functions for the logistic distribution using MLX.

Usage

mlx_dlogis(x, location = 0, scale = 1, log = FALSE)

mlx_plogis(x, location = 0, scale = 1)

mlx_qlogis(p, location = 0, scale = 1)

Arguments

x

Vector of quantiles (mlx array or coercible to mlx)

location, scale

Location and scale parameters (default: 0, 1)

log

If TRUE, return log density for mlx_dlogis (default: FALSE)

p

Vector of probabilities (mlx array or coercible to mlx)

Value

An mlx array with the computed values.

Examples

x <- as_mlx(seq(-3, 3, by = 0.5))
