We consider the problem of claims reserving and estimating run-off triangles. We generalize the gamma cell distributions model which leads to Tweedie’s compound Poisson model. Choosing a suitable parametrization, we estimate the parameters of our model within the framework of generalized linear models (see Jørgensen-de Souza [2] and Smyth-Jørgensen [8]). We show that these methods lead to reaso...

purpose: to report a case of hermansky-pudlak syndrome (hps). case report: a 7-year-old boy presented with marked generalized hypopigmentation, eye deviation and nystagmus. in addition he had history of easy bruising. visual acuity was 20/200. he had markedly translucent green irides, hypermetropic astigmatism, horizontal nystagmus and marked exotropia. funduscopy revealed a hypopigmented retin...

In recent years, new techniques based on artificial intelligence and machine learning in particular have been making a revolution the work of actuaries, including loss reserving. A particularly promising technique is that neural networks, which shown to offer versatile, flexible accurate approach However, applications networks reserving date primarily focused (important) problem fitting central...

In this paper we examine the claims reserving problem using Tweedie’s compound Poisson model. We develop maximum likelihood and Bayesian Markov chain Monte Carlo simulation approaches to fit the model and then compare estimated models under different scenarios. The key point we demonstrate relates to comparison of reserving quantities with and without model uncertainty incorporated into the pre...
