BACKGROUND To present an episodic random utility model that unifies time trade-off and discrete choice approaches in health state valuation. METHODS First, we introduce two alternative random utility models (RUMs) for health preferences: the episodic RUM and the more common instant RUM. For the interpretation of time trade-off (TTO) responses, we show that the episodic model implies a coeffic...

The aim of the present study was the estimation of (co) variance components and genetic parameters for body weight of Moghani sheep, using random regression models based on B-Splines functions. The data set included 9165 body weight records from 60 to 360 days of age from 2811 Moghani sheep, collected between 1994 to 2013 from Jafar-Abad Animal Research and Breeding Institute, Ardabil province,...

For this situation, analytical mathematical models typical connections cells have been developed. Using developed models, cu...

In this paper I propose new continuous and discrete choice demand models. To do so, I note that existing demand models from the continuousand discrete-choice demand literatures each have distinct advantages for taking to market-level data. I attempt to build models with the union of the good properties of each literature. For instance, the continuous choice models are more appropriate for disag...

In conventional random-utility models, such as the multinomial logit model, it is assumed that a decisionmaker's choice set is independent of his or her preferences conditional on the explanatory variables of the models. However, there are many situations in which the decisionmaker chooses the choice set, thereby making the independence assumption implausible. For example, if information about ...

Computer models are widely used to help make decisions about real-world systems. As computer of large and complex systems can have long run-times high-dimensional input spaces, it is often necessary use emulation assess uncertainties in model output. This paper presents methodology for motivated by a example energy policy. The studied an economic investment electricity generation Great Britain....
