Promotions are becoming more important and prevalent in e-commerce to attract customers boost sales, leading frequent changes of occasions, which drives users behave differently. In such situations, most existing Click-Through Rate (CTR) models can’t generalize well online serving due distribution uncertainty the upcoming occasion. this paper, we propose a novel CTR model named MOEF for recomme...

One way in which marketers gain insights about consumers is by identifying the occasions in which consumers use their products and which are invoked by their products. Identifying occasions helps in consumer segmentation, answering why consumers purchase a product, and where and when they use it. Additionally, the types of occasions a consumer participates in and the social settings surrounding...

Longitudinal data, often called repeated measurements in medicine and panel data in the social sciences, arise when units provide responses on multiple occasions. Such data can be thought of as clustered or two-level data with occasions i at level 1 and units j at level 2. One feature distinguishing longitudinal data from other types of clustered data is the chronological ordering of the respon...

Obesity is a global public health priority. Restrained eating is related to obesity and total energy intake but associations with the eating patterns are unclear. We examined the associations of restrained eating with the size and frequency of intake occasions among 1213 British adult (19-64 y) participants in a cross-sectional analysis of the UK National Diet and Nutrition Survey 2000. The Dut...

A relevant methodology to summarize three-way data is three-mode factor analysis (T3) (Tucker, 1966) where units, variables and occasions are reduced into a small number of components. Although in multivariate analyses variables and occasions are often summarized by factorial methodologies, units are more frequently partitioned into a few homogeneous classes by a clustering technique. This can ...

There is a growing body of scientific literature examining the effects alcohol mixed with energy drink (AMED) on consumption and related negative consequences, such as risky behavior or health effects. It unknown whether differences in cultural context may influence these AMED The current cross-cultural study compared data N = 6881 students from Netherlands (N 4424), UK 1594), Australia 863). D...

This study aims to investigate the effects of violations of the sphericity assumption on Type I error rates for different methodical approaches of repeated measures analysis using a simulation approach. In contrast to previous simulation studies on this topic, up to nine measurement occasions were considered. Therefore, two populations representing the conditions of a violation vs. a non-violat...
