NettetFor example, a correlation of r = 0.9 suggests a strong, positive association between two variables, whereas a correlation of r = -0.2 suggest a weak, negative association. A correlation close to zero suggests no linear association between two continuous variables. It is important to note that there may be a non-linear association between two ...

This would give a piecewise-linear model, rather than a piecewise-constant one. If we’ve built the tree well, however, there are only a few, closely-spaced points in each leaf, so the regression surface would be nearly constant anyway. 2 lalala meme download

NettetIn answering this question on discrete and continuous data I glibly asserted that it rarely makes sense to treat categorical data as continuous. ... But if I use linear regression, then I am making very strong assumptions about the relative difference between consecutive values of the ordinal variable, and I'm usually reluctant to do that. NettetLinear regression predicts a continuous value in (-inf, inf) and logistic regression predicts a continuous probability in [0, 1]. We use logistic regression for classification through the use of a threshold, e.g. if the probability given by the logistic regression is >= 0.6 then we will classify it as 1, and 0 otherwise.
