R / mgcv: te () ve ti () tensör ürünleri neden farklı yüzeyler üretir?
mgcvİçin paket Rtensör ürün etkileşimleri uydurma için iki işlevi vardır: te()ve ti(). İkisi arasındaki temel işbölümünü anlıyorum (doğrusal olmayan bir etkileşime uymak ve bu etkileşimi ana etkilere ve etkileşime ayırmak). Anlamadığım şey neden te(x1, x2)ve ti(x1) + ti(x2) + ti(x1, x2)(biraz) farklı sonuçlar üretebilir. MWE (uyarlanmıştır ?ti): require(mgcv) test1 <- …
