In Monte Carlo simulations, it is a commonly used procedure to generate synthetic data based on a large survey (e.g. a microcensus) first. These synthetic data is then used as universe/population for the simulation study. Out of this universe, samples are drawn repeatedly and estimates of interest are evaluated (e.g. sampling designs or imputation methods).
Examples for this procedure can be found below:
I am wondering if it is possible to skip this generation of synthetic data and use real data as universe. To be specific: I have a large data set with 300,000 observations. Is it possible to use this data set as universe for my Monte Carlo simulation and draw repeatedly a sample, of e.g. 20,000 observations, out of this universe? Or do I need to generate a larger synthetic data set first?
The goal of the Monte Carlo simulation study is an evaluation of several imputation methods based on different missing data mechanisms. I want to make conclusions, which of the imputation methods are best for this survey.
Any advice or references are appreciated!
