regression analysis

(in statistics) a test in which the size of one variable (the dependent variable) is dependent on another (the independent variable). Often the relationship is a linear one, enabling a line of best fit to be drawn on a SCATTER DIAGRAM.

Like Larry Gonick's Cartoon Guide to Statistics, The Manga Guide to Regression Analysis similarly helps students grasp the meaning of R-squared, correlation coefficients, and null hypotheses -- terms that have proved to be the bane of many students' college careers.
From previous (and new) experiments, the data sets are arranged so as to fit the optimal curve by regression analysis; the BPNN is also trained to develop a knowledge database until the learning structure is robust.
