Which statement is TRUE regarding a generalized additive model (GAM) in SAS Visual Analytics?
A. GAM assumes a strict linear relationship between the predictors and the response function.
B. The roughness penalty controls the balance between goodness of fit and the roughness of the spline curve.
C. Specification of a spline effect is optional.
D. A larger maximum degrees of freedom for the univariate spline term enforces a less complex fit.
