Probability density function transformation
WebbConceptual development. The idea of the probit function was published by Chester Ittner Bliss in a 1934 article in Science on how to treat data such as the percentage of a pest killed by a pesticide. Bliss proposed transforming the percentage killed into a "probability unit" (or "probit") which was linearly related to the modern definition (he defined it … Webbdensity is f(x 1;x 2) = 1 for 0 x 1 1 and 0 x 2 1. Let Y = X 1 1X 2. We want P 2 <1 2. Note that we don’t need the density of Y to answer the question: since the joint density of X 1 and X 2 is constant on the unit square, the probability P 1 2 <1 2 is equal to the area of the shaded region Rin the following gure.
