WebFeb 6, 2024 · We used Cragg hurdle exponential regression models controlling for past service use, demographics, length of enrollment, and county. Results We found that using preventive services in 2005‐2007 was associated with higher likelihood and number of treatment dental services used, but associated with lower treatment expenditures in 2008. WebJul 13, 2016 · As an example of second generation model, this chapter introduces a class of models known as Double Hurdle Models (originally proposed by Cragg ( 1971 )), which allows the potential attrition and the extent of attrition to be modeled separately. We develop an attrition model using a double hurdle model for a European auto portfolio.
