Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Students in linear models courses and data analysts usually rely upon intuition and/or trial and error methods to determine estimability. We suggest reducing the design matrix to row echelon form as a ...

We establish the convergence theories of the symmetric relaxation methods for the system of linear equations with symmetric positive definite coefficient matrix, and more generally, those of the ...

Figure 3.5.2. The derivative Use a linear approximation to estimate f (0.9) f (0.9) and f (1.1). f (1.1) . Are your estimates in part (a) too large or too small? State Newton's iterative formula that ...

Nonlinear regression is a form of regression analysis in which data fit to a model is expressed as a mathematical function.

A linear relationship (or linear association) is a statistical term used to describe the directly proportional relationship between a variable and a constant.
