Re: Ridge (Ridge Regression and Ridge Trace)

If there is no @resample equivalent for matrices do you have any hints on how to bootstrap in pairs? This pairs bootstrap apprach can be used for: taking care of heteroskedasticity: y1(t) = b0 + b1 * x1(t) + e1(t) where I want to resample pairs of y(t) and x(t), e.g. y(9) together with x(9), y(11) t...
