multipleSyn: Generate synthetic micro datasets

In synMicrodata: Synthetic Microdata Generator

Generate synthetic micro datasets

Description

Generate synthetic micro datasets using a hierarchically coupled mixture model with local dependence (HCMM-LC).

Usage

multipleSyn(data_obj, model_obj, n_burnin, m, interval_btw_Syn, show_iter = TRUE)

## S3 method for class 'synMicro_object'
print(x, ...)

Arguments

data_obj	data object produced by readData.
model_obj	model object produced by createModel.
n_burnin	size of burn-in.
m	number of synthetic micro datasets to be generated.
interval_btw_Syn	interval between MCMC iterations for generating synthetic micro datasets.
show_iter	logical value. If TRUE, multipleSyn will print history of (r,s,k) components on console.
x	object of class synMicro_object; a result of a call to multipleSyn().
...	further arguments passed to or from other methods.

Value

multipleSyn returns a list of the following conmponents:

synt_data	list of m synthetic micro datasets.
comp_mat	list of matrices of the mixture component indices.
orig_data	original dataset.

Examples

## preparing to generate synthetic datsets
Y_demo <- data.frame(
  Sepal.Length = iris$Sepal.Length,
  Sepal.Width  = iris$Sepal.Width,
  Petal.Length = iris$Petal.Length,
  Petal.Width  = iris$Petal.Width
)

X_demo <- data.frame(
  Species = iris$Species
)

dat_obj <- readData(Y_input = Y_demo, X_input = X_demo)
mod_obj <- createModel(dat_obj, max_R_S_K=c(30,50,20))

## generating synthetic datasets
res_obj <- multipleSyn(dat_obj, mod_obj, n_burnin = 100, m = 5, 
                       interval_btw_Syn = 50, show_iter = FALSE)

print(res_obj)
