Witrynaas: ( Y 1 Y 2 ⋮ Y N) = ( 1 x 1 1 x 2 ⋮ 1 x N) ( β 0 β 1) + ( ε 1 ε 2 ⋮ ε N) or simply: Y = X β + ε. The design matrix is the matrix X. Once we define a design matrix, we are ready to find the least squares estimates. We refer to this as fitting the model. For fitting linear models in R, we will directly provide a formula to the lm ...
