Understanding Regression Lines

A regression line in Excel showcases the linear relationship between variables. It's a statistical tool used in various fields like finance to demonstrate correlations and predict trends. Excel's linear regression, or ordinary least squares (OLS) regression, is pivotal for determining factor weights in models such as Fama-French and CAPM.

Creating a Regression Line Graph

To create a regression line graph, you need a chart that supports trendlines like XY scatter or line graphs. Excel cannot add regression lines to 3-D, stacked, pie, or radar charts. Use Excel's Data Analysis ToolPak for a streamlined process and interpret the regression output to gauge the correlation strength and size.

Adding the Regression Line

After plotting your data, right-click on the data series and select 'Add Trendline'. Choose 'Linear' under the trendline options to insert a linear regression line. Excel uses the least squares method to ensure the best fit line for your data points, reflecting the relationship between your independent and dependent variables.

Forecasting with Trendlines

Trendlines in Excel, including linear, polynomial, and exponential, can extend beyond the graph to forecast future trends. This feature is particularly useful in analyzing and predicting economic data and asset prices.

Customizing Regression Lines

Customize your regression line by adjusting its color, thickness, and style. You can also format the axis values to better represent the data's scale and range. Detailed tutorials for these customizations are available on our website under the Excel Charts and Graphs category.
