Phantom distribution functions for some stationary sequences [PDF]

, 2015
The notion of a phantom distribution function (phdf) was introduced by O'Brien (1987). We show that the existence of a phdf is a quite common phenomenon for stationary weakly dependent sequences.

Polyethylene tarping elevates temperature and reduces emergence of Phloeosinus punctatus LeConte (Coleoptera: Curculionidae) from giant sequoia debris piles

Agricultural and Forest Entomology, EarlyView.
Phloeosinus bark beetles may build up large populations in branch debris piles and stress giant sequoia trees. Covering debris piles with polyethylene sheeting increased the mean ambient temperature in piles and reduced beetle emergence. This was mediated by canopy structure, where ambient temperatures were further elevated under open canopies.

Estimations on the Generalized Exponential Distribution Using Grouped Data [PDF]

, 2010
Classical and Bayesian estimators are obtained for the shape parameter of the Generalized-Exponential distribution under grouped data. In Bayesian estimation, three types of loss functions are considered: the Squared Error loss function which is ...

A tutorial on Bayesian model averaging for exponential random graph models

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract The use of exponential random graph models (ERGMs) is becoming prevalent in psychology due to their ability to explain and predict the formation of edges between vertices in a network. Valid inference with ERGMs requires correctly specifying endogenous and exogenous effects as network statistics, guided by theory, to represent the network ...

Analysis of Reliability Characteristics of Bathtub-Shaped Distribution Under Adaptive Type-I Progressive Hybrid Censoring

IEEE Access, 2020
In reliability and life testing experiments, obtaining complete data still consumes lots of time, financial and human supports. A censoring scheme which can have balance between the total testing time, the used number of units and cost in life tests is ...

A study on Bayesian estimation of parameters of some well known distribution functions [PDF]

, 2014
The thesis addresses the problem of estimation of parameters of some well known distribution functions. The problem of estimation of parameters of binomial, Poisson, normal and exponential distribution function has been considered.

A Bayes factor framework for unified parameter estimation and hypothesis testing

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract The Bayes factor, the data‐based updating factor of the prior to posterior odds of two hypotheses, is a natural measure of statistical evidence for one hypothesis over the other. We show how Bayes factors can also be used for parameter estimation.

A multilevel Ornstein–Uhlenbeck process with individual‐ and variable‐specific estimates as random effects

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract In the present study, we extend a stochastic differential equation (SDE) model, the Ornstein–Uhlenbeck (OU) process, to the simultaneous analysis of time series of multiple variables by means of random effects for individuals and variables using a Bayesian framework.

The Impact of Risk Exposure and Environmental Conditions on European Banking Efficiency

European Financial Management, EarlyView.
ABSTRACT This study investigates the determinants of bank cost efficiency in Europe by applying a dynamic Bayesian stochastic frontier approach. We distinguish between two conceptually and empirically separate components of efficiency: (1) an intrinsic component, driven by internal bank features such as size and risk exposure, and (2) an extrThis study
