Comparing penalized splines and fractional polynomials for flexible modelling of the effects of continuous predictor variables
Strasak, Alexander M.; Umlauf, Nikolaus; Pfeiffer, Ruth M. - In: Computational Statistics & Data Analysis 55 (2011) 4, pp. 1540-1551
P(enalized)-splines and fractional polynomials (FPs) have emerged as powerful smoothing techniques with increasing popularity in applied research. Both approaches provide considerable flexibility, but only limited comparative evaluations of the performance and properties of the two methods have...

Nonlife ratemaking and risk management with Bayesian generalized additive models for location, scale, and shape
Klein, Nadja; Denuit, Michel; Lang, Stefan; Kneib, Thomas - In: Insurance: Mathematics and Economics 55 (2014) C, pp. 225-249
Generalized additive models for location, scale and, shape define a flexible, semi-parametric class of regression models for analyzing insurance data in which the exponential family assumption for the response is relaxed. This approach allows the actuary to include risk factors not only in the...

A Bias in the Prediction of Tastes.
Loewenstein, George; Adler, Daniel - In: Economic Journal 105 (1995) 431, pp. 929-37
Recent research has documented an 'endowment effect' whereby people become more attached to objects they receive than would be predicted from their prior desire to possess the object. In two experiments, the authors test whether people are aware of the effect--whether they realize that they will...
