2 Αυγ 2019 · A trendline (or line of best fit) is a straight or curved line which visualizes the general direction of the values. They're typically used to show a trend over time. In this article, we'll cover how to add different trendlines, format them, and extend them for future data.
The Least Squares Regression Calculator is biased against data points which are located significantly away from the projected trend-line. These outliers can change the slope of the line disproportionately. On a similar note, use of any model implies the underlying process has remained 'stationary' and unchanging during the sample period.
