Quantile estimation under possibly misspecified generalised linear model
The following paper deals with the asymptotic behaviour of the maximum likelihood estimator in a misspecified generalised linear model. Of particularly interest is the estimation of a quantile in dose-response curves. Using asymptotic properties of the maximum likelihood estimator under misspecification of the model, these results are applied to quantile estimation for dose-response curves. Consistency and asymptotic normality are established.Generalised linear model Maximum likelihood estimator Dose-response curves Quantile estimation

Cross-country comparison of pomegranate juice acceptance in Estonia, Spain, Thailand, and United States
The objective of this study was to compare acceptance of different flavor combinations across countries, determine consumer clusters across countries and identify drivers of liking for a healthy product (pomegranate juice). Five pomegranate juices varying in flavor character were evaluated by consumers in Estonia, Spain, Thailand, and the United States. In this study the consumers evaluated overall acceptability and flavor, sweet, sour, fruity, and pomegranate flavor liking. Also, Just About Right (JAR) questions were answered for those same attributes. The results suggested that although some samples varied in their liking across countries, larger differences in acceptance were found between consumer clusters across countries. These data suggest that individual consumer variation is greater than country specific variation. In addition, factors such as taste sensitivity or prior exposure rather than flavor are important in acceptability of pomegranate juices
