About this document
Linear Models and Matrix Algebra by straffor is a document available to read on EtoBox.
The chapter introduces matrix algebra and its applications to linear models. Matrix algebra allows equation systems to be written compactly using matrices. It also enables testing for a solution via determinants and finding solutions through multiplication if a solution exists. Matrix operations like addition, subtraction, and multiplication are defined. Matrix multiplication requires the number of columns in the first matrix to equal the number of rows in the second. The product of matrix multiplication is
