Deming regression (total least squares) also finds a line that fits a set of two-dimensional sample points, but (unlike ordinary least squares, least absolute deviations, and median slope regression) it is not really an instance of simple linear regression, because it does not separate the coordinates into one … Se mer In statistics, simple linear regression is a linear regression model with a single explanatory variable. That is, it concerns two-dimensional sample points with one independent variable and one dependent variable (conventionally, … Se mer Description of the statistical properties of estimators from the simple linear regression estimates requires the use of a statistical model.

That is exactly what the above equation does. If the slope is negative at the particular point, the second term gets added to the value of weights in previous iteration.
