LINEARREG_ANGLE

Summary

The angle, in degrees, of the least-squares best-fit line over the last N points. It is the LINEARREG_SLOPE value passed through atan and converted to degrees. Positive angle = rising fit line, negative = falling; magnitude reflects steepness.

Formula

m = (N·SumXY − SumX·SumY) / (SumX² − N·SumXSqr), with SumX=N(N−1)/2, SumXSqr=N(N−1)(2N−1)/6; angle = atan(m)·(180/π)

Inputs

inReal — Input series to regress

Outputs

outReal — Regression line slope expressed as an angle in degrees

Parameters

optInTimePeriod — Number of points in the regression window
