Who-is-a-Jew Algorithm

I present an algorithm that I developed to identify who was Jewish and who was not from among a population of immigrants who arrived in Ellis Island from the Russian Empire during the pre-WWI Age of Mass Migration. The algorithm has two main steps: Determine how “Jewish” were each first name and last name Determine whether each immigrant was Jewish or not based on his first and last names I explain how this algorithm works and show evidence indicating that this identification process works well.
