Sampling techniques

Square root biased sampling

Square root biased sampling is a sampling method proposed by William H. Press, a computer scientist and computational biologist, for use in airport screenings. It is the mathematically optimal compromise between simple random sampling and strong profiling that most quickly finds a rare malfeasor, given fixed screening resources. Using this method, if a group is times as likely as the average to be a security risk, then persons from that group will be times as likely to undergo additional screening. For example, if someone from a profiled group is nine times more likely than the average person to be a security risk, then when using square root biased sampling, people from the profiled group would be screened three times more often than the average person.

Variance: Why n-1? Intuitive explanation of concept and proof (Besselβ€˜s correction)

You might have learned that in some instances you don't divide by n when you calculate the empirical variance of your data but by n-1. This is known as Bessel's correction. In this video, I will explain when to use it, why we need a correction in the first place, and why this correction ha
