Tidy Randomly Generated Zero Truncated Geometric Distribution Tibble

Source: R/random-tidy-zero-trunc-geometric.R
tidy_zero_truncated_geometric.Rd

This function will generate n random points from a zero truncated Geometric distribution with a user provided, .prob, 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_geometric(
  .n = 50,
  .prob = 1,
  .num_sims = 1,
  .return_tibble = TRUE
)

Arguments

.n

The number of randomly generated points you want.

.prob

A probability of success in each trial 0 < prob <= 1.

.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.

Value

A tibble of randomly generated data.

Details

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