APLIKASI MODEL REGRESI SEMIPARAMETRIK SPLINE TRUNCATED (Studi Kasus: Pasien Demam Berdarah Dengue (DBD) di Rumah Sakit Puri Raharja)
Abstract: Semiparametric
regression is a regression model that includes parametric components and
nonparametric components in a model. The regression model in this research is
truncated spline semiparametric regression with case studies of patients with
Dengue Hemorrhagic Fever (DHF) at Puri Raharja Hospital during the period of
January to March 2015. The best regression model estimation is obtained from
the selection of optimal knots which has minimum Generalized Cross Validation
(GCV) is. Parametric components in this research include age (years), body
temperature (0C), platelets and hematocrit (%) as a nonparametric component.
The minimum value of GCV is 0.03552045 achieved at the point of 39.6 knots, MSE
value of 0.0296922; and the value of coefficient determination is 98.91%,
obtained from semiparametric regression model truncated linear spline (order 2)
with a single point of knots.
Keywords: GCV; knots;
semiparametric regression; spline
