    $\begingroup$ As a statistician I very rarely standardise data and I don't know any other statisticians that do. $\endgroup$ Commented Mar 15, 2021 at 13:13
  • $\begingroup$ Technically, for OLS, apart from the interpretation of the relative coefficient size, standardisation and centering don't make a difference, due to the equivariance properties of OLS. This is different for some other methods such as Lasso. $\endgroup$ Commented Mar 15, 2021 at 13:14
  • $\begingroup$ @RobertLong Very rarely? I can understand linear models, but there are many models which work better with standardized or normalized variables, for ex. everything having to do with distances. $\endgroup$ Commented Mar 15, 2021 at 13:50

    $\begingroup$ @user2974951 the question is about linear regression, so that's what I was referring to. $\endgroup$ Commented Mar 15, 2021 at 15:40
