Outliers in INAR(1) models
integer-valued autoregressivemodels additive and innovational outliers conditionalleast squares estimators strong consistency
2010/3/19
In this paper the integer-valued autoregressive model of order one, contaminated with
additive or innovational outliers is studied in some detail. Moreover, parameter estimation
is also addressed. S...
Identifying outliers in Bayesian hierarchical models: a simulation-based approach
Hierarchical models diagnostics outliers distributional assumptions
2009/9/22
A variety of simulation-based techniques have been proposed for detec-
tion of divergent behaviour at each level of a hierarchical model. We investigate a
diagnostic test based on measuring the coni...
Propagation of outliers in multivariate data
Breakdown point contamination model independent contamination influence function robustness
2010/3/18
We investigate the performance of robust estimates of multivariate
location under nonstandard data contamination models such as
componentwise outliers (i.e., contamination in each variable is indepe...
A new graphical tool of outliers detection in regression models based on recursive estimation

2010/4/30
We present in this paper a new tool for outliers detection in the context of multiple regression models. This graphical tool is
based on recursive estimation of the parameters. Simulations were carri...
