Source: R/distribution.R

[Experimental]

Determines whether a probability distribution is symmetric around its center.

has_symmetry(x, ...)

Arguments

x

The distribution(s).

...

Additional arguments used by methods.

Value

A logical value indicating whether the distribution is symmetric.

Examples

# Normal distribution is symmetric
has_symmetry(dist_normal(mu = 0, sigma = 1))
#> [1] TRUE
has_symmetry(dist_normal(mu = 5, sigma = 2))
#> [1] TRUE

# Beta distribution symmetry depends on parameters
has_symmetry(dist_beta(shape1 = 2, shape2 = 2))  # symmetric
#> [1] TRUE
has_symmetry(dist_beta(shape1 = 2, shape2 = 5))  # not symmetric
#> [1] FALSE
