# Confidence band for a regression line.

### What is it about?

Regression attempts to estimate the typical value of some variable Y, given some value for the variable X. The resulting estimate will be inaccurate, so a goal is compute an interval containing that contains the unknown typical value. Moreover, this is done in such a way that all of the intervals contain the true value with some specified probability.

### Why is it important?

Extant techniques make highly restrictive assumptions. The new method deals with these concerns resulting in a better understanding of how well a regression line, based on observed data, contains the true regression line if that would result if all individuals in the population under study were measured.
