func TestConfusionMatrixPrecisionAndRecall(t *testing.T) · Red recall

Read the equation

This relation defines Red recall in the source section “func TestConfusionMatrixPrecisionAndRecall(t *testing.T) · Red recall”. It specifies the displayed relationship between the named quantities or parameters. Its interpretation depends on the source’s stated variables and conditions; this record does not assign an unprovided physical or cognitive meaning to them.

Terms & definitions

The recovered passage does not supply a separate symbol table. Read the source context for the notation used in this version; familiar letters may carry different meanings in other builds.

Assumptions & limits

• This source expression was recovered from the pinned code revision. Its presence does not establish that the associated program was built, run, or scientifically validated.

Original context

	// Green recall = 2 / 2 = 1.0 (all expected Green are scored Green).
	rec := m.BandRecall(engine.BandGreen)
	if rec != 1.0 {
		t.Errorf("recall %v, want 1.0", rec)
	}

	// Red recall = 0 / 1 = 0.0 (the one expected Red was scored Green).
	redRec := m.BandRecall(engine.BandRed)
	if redRec != 0.0 {
		t.Errorf("red recall %v, want 0.0", redRec)
	}
}

Red recall = 0 / 1 = 0.0 (the one expected Red was scored Green).
