Tidy Randomly Generated Chisquare (Non-Central) Distribution Tibble

Description

This function will generate n random points from a chisquare distribution with a user provided, .df, .ncp, 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_chisquare(
  .n = 50,
  .df = 1,
  .ncp = 1,
  .num_sims = 1,
  .return_tibble = TRUE
)

Arguments

`.n`	The number of randomly generated points you want.
`.df`	Degrees of freedom (non-negative but can be non-integer)
`.ncp`	Non-centrality parameter, must be non-negative.
`.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 stats::rchisq(), and its underlying p, d, and q functions. For more information please see stats::rchisq()

Value

A tibble of randomly generated data.
