Evaluating yield models for crop insurance rating

Lanoue, Christopher - 2010

Crop insurance performance and loss rates depend directly on underlying crop yield distributions. However, there still exists much debate about how to represent the underlying crop yield distributions. Using farm-level corn and soybean yields from 1972-2008, this study examines in-sample...

Evaluating Yield Models for Crop Insurance Rating

Lanoue, Christopher; Sherrick, Bruce J.; Woodard, Joshua D. - 2010

Generated crop insurance rates depend critically on the distributional assumptions of theunderlying crop yield loss model. Using farm level corn yield data from 1972-2008, we revisitthe problem of examining in-sample goodness-of-fit measures across a set of flexibleparametric, semi-parametric,...

Global Income Distribution and Inequality: 1993 and 2000

Chotikapanich, Duangkamon; Griffiths, William E; Rao, … - Department of Economics, Faculty of Business and Economics - 2009

The nature of global and regional income distributions and the extent of inequality are examined using country-level data on income distributions drawn from World Bank studies and the World Institute for Development Economics Research for the period 1993 - 2000. Beta-2 income distributions are...

Matrix variate slash distribution

Bulut, Y. Murat; Arslan, Olcay - In: Journal of Multivariate Analysis 137 (2015) C, pp. 173-178

In this paper, we introduce a matrix variate slash distribution as a scale mixture of the matrix variate normal and the uniform distributions. We study some properties of the proposed distribution and give maximum likelihood (ML) estimators of its parameters using EM algorithm. We provide an...

Variance-mean mixture of the multivariate skew normal distribution

Arslan, Olcay - In: Statistical Papers 56 (2015) 2, pp. 353-378

In this paper, we introduce a new class of multivariate distributions as an extension of the normal variance–mean mixture distributions class. The new class results from a variance-mean mixture of the skew normal and the generalized inverse Gaussian distributions. The new class is very...

A credibility-based Erlang mixture model for pricing crop reinsurance

Porth, Lysa; Zhu, Wenjun; Seng Tan, Ken - In: Agricultural Finance Review 74 (2014) 2, pp. 162-187

/methodology/approach – The generating process of the historical loss cost ratio's (LCR's) are reviewed, and the Erlang mixture distribution is … proposed. A modified credibility approach is developed based on the Erlang mixture distribution and the liability weighted LCR … sector in Canada is used to show that the Erlang mixture distribution captures the tails of the data more accurately compared …
