Linear Functions . Mathematically similar to a linear relationship is the concept of a linear function. In one variable, a linear function can be written as follows: ...

The same thing would be true for the first function above, f(x) = x²: n² would equal n.This would be a weird mathematics indeed (there are algebras in which this happens for some nonunit ...

You might have millions of variables and millions of equations, but each equation might only involve a small number of the overall variables. These types of linear systems are called “sparse,” ...

So, let me assume that my best fit linear function has the form: Let me generically label the data as ( x i, y i). So, I can write d i and d i 2 as: Well that is just great. Now what?
