Tidy Randomly Generated Generalized Beta Distribution Tibble
Source:R/random-tidy-general-beta.R
tidy_generalized_beta.RdThis function will generate n random points from a generalized beta
distribution with a user provided, .shape1, .shape2, .shape3, .rate, and/or
.sclae, 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_numberThe current simulation number.xThe current value ofnfor the current simulation.yThe randomly generated data point.dxThexvalue from thestats::density()function.dyTheyvalue from thestats::density()function.pThe values from the resulting p_ function of the distribution family.qThe values from the resulting q_ function of the distribution family.
Usage
tidy_generalized_beta(
.n = 50,
.shape1 = 1,
.shape2 = 1,
.shape3 = 1,
.rate = 1,
.scale = 1/.rate,
.num_sims = 1,
.return_tibble = TRUE
)Arguments
- .n
The number of randomly generated points you want.
- .shape1
A non-negative parameter of the Beta distribution.
- .shape2
A non-negative parameter of the Beta distribution.
- .shape3
A non-negative parameter of the Beta distribution.
- .rate
An alternative way to specify the
.scaleparameter.- .scale
Must be strictly positive.
- .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::rbeta(), and its underlying
p, d, and q functions. For more information please see stats::rbeta()
