tidy_poisson: Tidy Randomly Generated Poisson Distribution Tibble

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

Tidy Randomly Generated Poisson Distribution Tibble

Description

This function will generate n random points from a Poisson distribution with a user provided, .lambda, and number of random simulations to be produced. The function returns a tibble with the simulation number column the x column which corresponds to the n randomly generated points, the d_, p_ and q_ data points as well.

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_poisson(.n = 50, .lambda = 1, .num_sims = 1)

Arguments

.n	The number of randomly generated points you want.
.lambda	A vector of non-negative means.
.num_sims	The number of randomly generated simulations you want.

Details

This function uses the underlying stats::rpois(), and its underlying p, d, and q functions. For more information please see stats::rpois()

Value

A tibble of randomly generated data.
