Chapter 1 Simple Linear Regression
... variables X and Y in science are fixed. A commonly used equation is Y=f(X), where f is certain function. Thus, given the value of X, the exact value of Y can be obtained via this equation. However, in the real world, based on the data obtained, it is almost impossible to obtain the fixed equation as ...
