> The ML world has collapsed on the terms X and y. (With that > capitalization). The ML community will probably use 3rd party packages for their linear regressions in any case. In my estimation, the ML community would be comfortable with any of these pairs of terms: Fine: + regressor, dependent_variable + independent_variable, dependent_variable + x, y Bad: + X, y <- this wouldn't makes sense here since the first argument is always a vector and is never a matrix. Often, capital letters indicate matrices, and lower case letters indicate vectors (or scalars). The reason that X is often capitalized is because it indicates that X is an m-by-n matrix of several independent variables; whereas y is lowercase because it is a single vector for the dependent variable. Since this linear_regression(regressor, dependent_variable) function takes a vector for the independent variable (as opposed to allowing a matrix of multiple regressors), it's probably not appropriate to use `X` (capitalized). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue44151> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
