WebNormally distributed errors: Classical Linear models assume the errors of regression, also known as the residuals, are normally distributed with mean zero.This condition is also difficult to meet in real life. Non-correlated variables: Finally, the regression variables are assumed to be non-correlated with each other, and preferably independent of each other. Web3 okt. 2024 · For a simple linear regression, R2 is the square of the Pearson correlation coefficient. A high value of R2 is a good indication. However, as the value of R2 tends to increase when more predictors are added in the model, such as in multiple linear regression model, you should mainly consider the adjusted R-squared, which is a …
Web5 sep. 2014 · The trend may be linear or non-linear. However, generally, it is synonymous with the linear slope of the line fit to the time series.
