The square of the correlation coefficient is a measure of the accuracy of this technique, and it is often computed with the "least squares" method.
One assumption this method relies on is the preservation of homoscedasticity, which can be confirmed using a residual plot. An important value for this technique is equal to the r-value times the quotient of the standard deviations of the dependent and independent variables. The square of the correlation coefficient is a measure of the accuracy of this technique, and it is often computed with the "least squares" method. For 10 points, name this statistical technique used to fit a trendline to data.
