Linear Regression Slope [Slope]

Return to Complete List of Functions

The Linear Regression Slope function returns the slope component of a linear regression line of a field to time over a given number of periods. Parameters ------------------ Data          The data to use in the regression. This is typically 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 slope component is the value multiplied by the current bar to obtain the offset added to the intercept component to obtain the current value. The linear regression line at the beginning of a data series is not defined until there are enough values to fill the given period.
