Tidy Randomly Generated Inverse Gamma Distribution Tibble
Source:R/random-tidy-gamma-inverse.R
tidy_inverse_gamma.Rd
This function will generate n
random points from an inverse gamma
distribution with a user provided, .shape
, .rate
, .scale
, 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 ofn
for the current simulation.y
The randomly generated data point.dx
Thex
value from thestats::density()
function.dy
They
value from thestats::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.
Arguments
- .n
The number of randomly generated points you want.
- .shape
Must be strictly positive.
- .rate
An alternative way to specify the
.scale
- .scale
Must be strictly positive.
- .num_sims
The number of randomly generated simulations you want.
Details
This function uses the underlying actuar::rinvgamma()
, and its underlying
p
, d
, and q
functions. For more information please see actuar::rinvgamma()
