Fit a Top-k Oriented-Pair Panel Scorer

Fits a deterministic top-k oriented-pair scorer on a locked panel. Pair orientation is selected from the training data so that larger vote fractions indicate the positive class. This is a lightweight, auditable k-TSP-style scorer for small biomarker panels; it is not a full switchBox replacement.

Usage

os_ktsp_fit(X, y, k = 11L)

Arguments

X

Numeric matrix or data frame with samples in rows and features in columns.

y

Binary outcome vector. The second factor level is treated as positive.

k

Number of oriented pairs to retain.

Value

An object of class "os_ktsp_model".
