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)
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 |
data_gen_fn |
A function for data generation. Currently we can choose
either |
group_col_name |
The name of the grouping/label column to be created in the final data frame. |
Value
A data frame with the simulated data for all groups, including the grouping column.
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)
)
