simBKMRdata (version 0.1.1)

simulate_group_data: Simulate Group Data

Description

This function generates data for each group by invoking the specified data generation function once per group. It binds the generated data together into a single data frame.

Usage

simulate_group_data(param_list, data_gen_fn, 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 (mean, shape, rate, etc.). The list must be named with group names that match the groupings stated in group_col_name.

data_gen_fn

A function for data generation. Currently we can choose either generate_mvGamma_data or MASS::mvrnorm.

group_col_name

The name of the grouping/label column to be created in the final data frame.

Examples

# Example using MASS::mvrnorm for normal distribution
param_list <- list(
  Group1 = list(mean_vec = c(1, 2), sampCorr_mat = matrix(c(1, 0.5, 0.5, 1), 2, 2), sampSize = 100),
  Group2 = list(mean_vec = c(2, 3), sampCorr_mat = matrix(c(1, 0.3, 0.3, 1), 2, 2), sampSize = 150)
)
simulate_group_data(param_list, MASS::mvrnorm, "Group")

# Example using generate_mvGamma_data for Gamma distribution
param_list <- list(
  Group1 = list(sampCorr_mat = matrix(c(1, 0.5, 0.5, 1), 2, 2),
                shape_num = c(2, 2), rate_num = c(1, 1), sampSize = 100),
  Group2 = list(sampCorr_mat = matrix(c(1, 0.3, 0.3, 1), 2, 2),
                shape_num = c(2, 2), rate_num = c(1, 1), sampSize = 150)
)
simulate_group_data(param_list, generate_mvGamma_data, "Group")
