This document contains supplementary material to the paper “Fast smoothing parameter separation in multidimensional generalized P-splines: the SAP algorithm”. A description on how to obtain the derivatives of the approximate restricted maximum likelihood (REML) with respect to the variance components is given, as well as the closed-form expressions for maximum likelihood (ML) estimates of the v...

SUMMARY In dairy cattle breeding, genetic relationships among lactatio are of special interest because most selection operates on first la: This selection also complicates estimation of genetic Techniques which give estimates unbiased by selection should Estimation was done using EM-type REML for an animal relationships across herds. Records were from 3,070 Holstein cows the first lactation rec...

This handout describes the analysis of a repeated-measures experimental design with two crossed among-subjects factors and repeated-measures on a third (withinsubjects) factor. It presents the analysis described in the text: univariate ANOVA with the conservative F test, along with assessment of the validity of the model and with analysis of the effects. A later handout will present linear mixe...

OBJECTIVE Covariance functions (CF) are, in essence, the ‘infinite-dimensional’ equivalent to covariance matrices for traits measured repeatedly, potentially infinitely many times, along some continuous scale such as time or age. CFs produce a continuous description of the covariance structure over time, giving the covariance between any two ages as a function of the ages. DXMRR allows the esti...

In this paper two external schema generation algorithms are presented. These algorithms are defined in the framework of the new external schema definition methodology for OODBs put forward in (Samos, 1995); they generate an external schema from a set of classes selected from those existing in an external schema definition repository. Their main characteristic is that they avoid the generation o...

The project management discipline is expanding within many engineering activities. This discipline can facilitate strivings toward successful accomplishment of an engineering project. Therefore, many academic institutes teach the “project management” program. This study presents a novel approach that educates engineering students to become successful project managers based on contextual learnin...

Ambivalence, the presence of positive and negative reactions toward an object, typically involves the subjective experience of conflict. We investigate the role that the perceived validity of each side of an ambivalent attitude plays in producing subjective ambivalence (SA). Consistent with the metacognitive model of attitudes, we demonstrated that SA is reduced when people doubt either the pos...
