tidy_inverse_normal: Tidy Randomly Generated Inverse Gaussian Distribution Tibble

In TidyDensity: Functions for Tidy Analysis and Generation of Random Data

Tidy Randomly Generated Inverse Gaussian Distribution Tibble

Description

This function will generate n random points from an Inverse Gaussian distribution with a user provided, .mean, .shape, .dispersionThe function returns a tibble with the simulation number column the x column which corresponds to the n randomly generated points.

The data is returned un-grouped.

The columns that are output are:

• sim_number The current simulation number.

• x The current value of n for the current simulation.

• y The randomly generated data point.

• dx The x value from the stats::density() function.

• dy The y value from the stats::density() function.

• p The values from the resulting p_ function of the distribution family.

• q The values from the resulting q_ function of the distribution family.

Usage

tidy_inverse_normal(
  .n = 50,
  .mean = 1,
  .shape = 1,
  .dispersion = 1/.shape,
  .num_sims = 1
)

Arguments

.n	The number of randomly generated points you want.
.mean	Must be strictly positive.
.shape	Must be strictly positive.
.dispersion	An alternative way to specify the .shape.
.num_sims	The number of randomly generated simulations you want.

Details

This function uses the underlying actuar::rinvgauss(). For more information please see rinvgauss()

Value

A tibble of randomly generated data.
