Fit LS-SVR with RMSPE loss (Model 3) — internal

Internal fitter for the RMSPE LS-SVR family. Use psvr() with loss = "rmspe" instead. Returns the legacy psvr_rmspe shape; the deprecation wrapper rmspe_lssvr() forwards directly to this function.

Usage

.fit_rmspe(X, y, kernel, gamma, precondition = "auto")

Arguments

X, y, kernel, gamma, precondition

See rmspe_lssvr() for the full semantics of each argument (including the Remark-17 preconditioner).

Value

A list of class "psvr_rmspe" (legacy shape).
