simBKMRdata (version 0.1.1)

simulate_group_gamma: Simulate Group Multivariate Data

Description

This function generates data for each group from a Multivariate Gamma Distribution by invoking this distribution's random generator once per group. It binds the generated data together into a single data frame.

Usage

simulate_group_gamma(param_list, group_col_name)

Value

A data frame with the simulated data for all groups, including the grouping column.

Arguments

param_list

A list of named sublists, where each sublist contains the parameters for a group (sample size, mean, standard correlation matrix, shape, and rate parameter). The dimension of the parameters for each group must be the same.

group_col_name

The column name of the grouping/label column to be created in the final data frame. The values are taken from the names of the sublists of param_list. Defaults to "group". See the example below.

Examples

# Example using generate_mvGamma_data for MV Gamma distribution
param_list <- list(
 Male = list(
  sampSize = 100,
  sampCorr_mat = matrix(c(1, 0.5, 0.5, 1), 2, 2),  # Covariance matrix
  shape_num = c(2, 2),  # Shape parameters for Gamma distribution
  rate_num = c(1, 1)    # Rate parameters for Gamma distribution
 ),
 Female = list(
  sampSize = 150,
  sampCorr_mat = matrix(c(1, 0.3, 0.3, 1), 2, 2),
  shape_num = c(1, 4),
  rate_num = c(0.5, 2)
 )
