Many if not most of the examples on this page were apparently translated blindly from a single incorrect example
Multiple regression, as mentioned in the description, is where the X input is a N-dimensional array; a matrix of two or more
== History of error ==
* The very first example, [https://rosettacode.org/wiki/Multiple_regression?oldid=121951 Ruby], was incorrect -- it only used a single-axis X input, when the task description clearly said "x is given to you as a two-dimensional array".
* The next example added, [https://rosettacode.org/wiki/Multiple_regression?oldid=121955 Tcl], introduced the single-axis height/weight example. Things sort of went all to heck from there, with other languages cargo-culting the incorrect example from Tcl.
== Examples of multiple regression ==
Think of multiple regression as "surface fitting" rather than curve fitting. Some examples:
