tidy_zero_truncated_poisson {TidyDensity}

Tidy Randomly Generated Zero Truncated Poisson Distribution Tibble

Description

This function will generate n random points from a Zero Truncated 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_zero_truncated_poisson(
  .n = 50,
  .lambda = 1,
  .num_sims = 1,
  .return_tibble = TRUE
)

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.

.return_tibble

A logical value indicating whether to return the result as a tibble. Default is TRUE.

Details

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

Value

A tibble of randomly generated data.
