Linear regression and the normality assumption
discovery.ucl.ac.ukLinear regression models with residuals deviating from the normal distribution often still produce valid results (without performing arbitrary outcome transformations), especially in large sample size settings (e.g., when there are 10 observations per parameter).

Finally, one of the great advantages of mulitple regression models is that they allow for the inclusion of control variables. Control variables not only help ...
Linear regression: before and after fitting the model
vulstats.ucsd.eduLinear regression: before and after fitting the model It is not always appropriate to fit a classical linear regression model using data in their raw form. As we discuss in Sections 4.1 and 4.4, linear and logarithmic transformations can sometimes help in the interpretation of the model. Nonlinear
quantitative techniques - KASNEB Notes
kasnebnotes.co.kemodels are often approximated by linear ones. One of the applications of linear algebra is in finding solutions of simultaneous linear equations. the simplest case is when the number of unknowns is the same as the number of equations. One could begin with the problem of solving n simultaneous linear equations for n unknowns.

infosci.cornell.eduand logarithmic transformations. Further to this, trends can also be removed (e.g., by subtracting the overall mean of a time series), smoothing can be done by replacing the time series with a moving average, and other transformations may be useful as well (e.g., standardization or Box-Cox). In general, it is also good practice to clean
