RT Generic T1 Semiparametric models and P-splines A1 I., Currie, A1 M., Durbán, AB P-splines were introduced by Eilers and Marx (1996). We consider semiparametric models where the smooth part of the model can be described by P-splines. A mixed model representation is also considered. We set a simple strategy for the choice of P-spline parameters, ndx, bdeg and pord, and discuss the use of various criteria for smoothing parameter selection. We illustrate our remarks with the analysis of a randomised block design. YR 2001 FD 2001-03 LK https://hdl.handle.net/10016/158 UL https://hdl.handle.net/10016/158 LA eng DS e-Archivo RD 1 sept. 2024
