Linear Regression Functions in DAX

The video tutorial explains the use of Line St and Line SDX functions in DAX for computing linear regression. It covers how these functions return tables with multiple values and how to extract these values using the SelectColumns technique. The tutorial demonstrates creating measures to display linear regression lines in charts, focusing on the Line SDX function. It also discusses the implementation of linear regression using DAX, providing a step-by-step guide to creating a measure that calculates the slope and intercept for plotting a regression line.
