1. Longitudinal model for categorical data applied in an agriculture experiment about elephant grass
ABSTRACT Experiments where the response is a categorical variable are usually carried out in many fields such as agriculture. In addition, in some situations this response has three or more levels without an order between them characterizing a multinomial (nominal) response. Statistical models for scenarios where the observations of a nominal response can be

3. Regressão de dados binários : distribuição Weibull
In this work a new class of models for binary data based on Weibull distribution is introduced. A review is made of the most known linkage functions. This class of models has as special case the complementary log-log model and approximates well the logit and probit models. Three real data sets are given to compare the proposed model with many others. In one

7. Quality and provider choice: a multinomial logit-least-squares model with selectivity.
A Federal Trade Commission survey of contact lens wearers is used to estimate a multinomial logit-least-squares model of the joint determination of provider choice and quality of care in the contact lens industry. The effect of personal and industry characteristics on a consumer's choice among three types of providers--opticians, ophthalmologists, and optome

8. Determining provider choice for the treatment of mental disorder: the role of health and mental health status.
This article specifies and estimates a model of provider choice for mental health services. Three types of providers are identified: specialty mental health providers, general medical providers, and informal providers. Specific attention is paid to the role of health and mental health status in determining provider choice. The model is estimated using a mult
