Application of nonparametric discriminant analysis for assessing food safety issues of Caribbean imports

چکیده
Caribbean food imports often face detentions and refusals by the US resulting in a major loss of income. In this paper, we consider a classification procedure based on transvariation probabilities to correctly identify cases that lead to food detention. This is based upon several background variables on fourteen Latin American and Caribbean countries. A method for selecting variables according to their contribution towards predicting detention is given. For our particular sample, the selection method chose foreign direct investment as the variable that carried the most information in determining food detention. After removing variables that were non-informative about food detention status, a leave-one-out cross-validation shows that methods based on transvariation probabilities were superior to classical methods in predicting food detention.

متن کاملApplication of Discriminant Analysis to Estimate Instantaneous Maximum Discharge for Catchments in West of Iran
Accurate estimate of flood flows at selected return periods is a fundamental step in flood control and design of hydraulic structures. Due to the inadequacy or unavailability of flood flow records in several western catchments of Iran, traditional regional flood frequency methods lead to remarkable estimate errors, particularly for long return periods. In this research, discriminant analysis is...

In this paper, the financial efficiency of football clubs in English Premier League during 2016-17 season is determined. From a methodological perspective, we use Data Envelopment Analysis (DEA), a deterministic nonparametric frontier method. In particular, variable returns to scale and slack based measure are employed to assess whether teams are spending more resources than they need to achiev...
