There are simple linear regression calculators that use a “least squares” method to discover the best-fit line for a set of paired data. You then estimate the value of X (dependent variable) from Y (independent ...
Nettet10. des. 2024 · A3) Covariance doesn't measure non-linear relationships for the exact same reason it measures linear ones. Namely, that you can basically think of it as the slope in a linear equation (e.g. X = α Y + c ), so when you try and fit a line to a curve, the sum of square differences between the points and the line may be large.
