One Step to Efficient Synthetic Data. (arXiv:2006.02397v5 [math.ST] UPDATED)

A common approach to synthetic data is to sample from a fitted model. We show
that under general assumptions, this approach results in a sample with
inefficient estimators and whose joint distribution is inconsistent with the
true distribution. Motivated by this, we propose a general method of producing
synthetic data, which is widely applicable for parametric models, has
asymptotically efficient summary statistics, and is both easily implemented and
highly computationally efficient. Our approach allows for the construction of
both partially …
