What formulas are used to calculate the coefficients of multivariate linear regression using the stochastic gradient descent method?

Question

Mathematics

I am going to calculate multivariate linear regression coefficients in several ways, I need stochastic gradient descent. As far as I understand, the matrix form should be used there.

Answer 1

I understand that you are not allowed to use ready-made implementations. And that Google is also banned? Or was it blocked for you?
