Habitat assessments for biodiversity conservation are often complicated by the lack of detailed knowledge of a study species’ distribution. As an alternative to resource-intensive field-based methods to obtain such information, remotely sensed products can be utilized in species distribution models to infer a species’ distribution and ecological needs. Here we demonstrate how to arbitrate among...

We introduce a new approach to variable selection, called Predictive Correlation Screening, for predictor design. Predictive Correlation Screening (PCS) implements false positive control on the selected variables, is well suited to small sample sizes, and is scalable to high dimensions. We establish asymptotic bounds for Familywise Error Rate (FWER), and resultant mean square error of a linear ...

OBJECTIVES to examine the relationship between seven predictor variables (recorded on Day 3 of hospital admission) and discharge destination in non-elective medical patients aged 65+ years. DESIGN prospective cohort. SETTING eight centres in six European countries. PREDICTOR VARIABLES age, gender, living alone, physical function (three categories based on Barthel Index), cognition (Katzma...

I consider the estimation of linear regression models when the independent variables are measured with errors whose variances differ across observations, a situation that arises, for example, when the explanatory variables in a regression model are estimates of population parameters based on samples of varying sizes. Replacing the error variance that is assumed common to all observations in the...

This article describes a new non-parametric regression method that extends additive regression techniques to allow modeling of interactions among predictor variables. The proposed models consist of sums of smooth functions of one or more predictor variables. Each term involving more than one predictor is assumed to be a composition of bivariate functions of simpler terms in the model. The metho...

background: evidence indicates that sexual assertiveness is one of the important factors affecting sexual satisfaction. according to some studies, traditional gender norms conflict with women’s capability in expressing sexual desires. this study examined the relationship between gender roles and sexual assertiveness in married women in mashhad, iran. methods: this cross-sectional study was cond...

The study aimed to investigate students’ self-efficacy, self-esteem, and attitude as determinants of their writing performance. The participants for the study were 373 South Gonder Zone Preparatory School students who were chosen using multistage sampling technique. Questionnaire and writing test were employed to gather data. Pearson’s Correlation technique was used to analyze the associations ...
