Let A be an m × n matrix and let b be a vector in Rn. Here is a method for computing a least-squares solution of Ax = b: Compute the matrix ATA and the vector ATb. Form the augmented matrix for the matrix equation ATAx = ATb, and row reduce.
Nettet21. sep. 2016 · Because the model can be expressed as a generalized linear model ( see below ), for 0 < p < 1, ordinary least squares can suffice, with R-squared as the measure of goodness of fit in the fitting space. When p = 0 or 1 , more complex methods are required. The logistic regression model is: odds (Y=1) = p ( Y = 1) 1 − p ( Y = 1) = e θ …
