gamma_dist_def | R Documentation |
Generates a distribution definition when only parameter estimates
are available for gamma distributed parameters. See rgamma
for
distribution information.

)
shape |
Numeric, shape parameter of the gamma distribution. |
shape_sd |
Numeric, standard deviation of the shape parameter. |
scale |
Numeric, scale parameter of the gamma distribution. |
scale_sd |
Numeric, standard deviation of the scale parameter. |
mean |
Numeric, log mean parameter of the gamma distribution. |
mean_sd |
Numeric, standard deviation of the log mean parameter. |
sd |
Numeric, log sd parameter of the gamma distribution. |
sd_sd |
Numeric, standard deviation of the log sd parameter. |
max_value |
Numeric, the maximum value to allow. Defaults to 120. Samples outside of this range are resampled. |
samples |
Numeric, number of sample distributions to generate. |
A data.table defining the distribution as used by dist_skel
