Today I faced a term "finite samples" in reading Borusyak (2021)'s work:
We conclude the section by providing simulation evidence that the efficiency gains from using our estimator are sizable, that its sensitivity to some parallel trend vio- lations is no larger than that of the alternatives, and that our inference tools perform well in finite samples
I did a search about the "finite sample" and "infinite sample"
Sampling from an infinite population is handled by regarding the population as represented by a distribution. ... A random sample from an infinite population is therefore considered as a random sample from a distribution
It seems to me that regarding "finite sample", we randomly choose a sample in a population and analyze this population and draw a conclusion for a population, and in an "infinite sample", we test for the whole population data to draw a conclusion for the population, is it correct?
