Linear XY Regression Intercept [XY-Intercept]

Return to Complete List of Functions

The Linear XY Regression Intercept function returns the intercept component of a linear regression line between two fields over a given number of periods. Parameters ------------------ Independent Data    One set of data to use in the regression, typically the known or controlling value in the pair.                                  This is typically a field in a data series or a calculated value. Dependent Data      The other set of data to use, typically dependent on the independent data.                                  Also a field in a data series or a calculated value. Period                       The number of bars of data to include in the regression, including the current value.                                  For example, a period of 3 includes the current value and the two previous values. Function Value ------------------------ A linear regression line is a straight line which is as close to all of the given values as possible. The intercept component is the value of the dependent data on that line when the independent data is 0. The linear regression line at the beginning of a data series is not defined until there are enough values to fill the given period.
