Outliers in time series can wreak havoc with conventional least-squares procedures, just as in the case of ordinary regression. This paper presents two time-series outlier models, points out their ordinary regression analogues and the corresponding outlier patterns, and presents robust alternatives to the least-squares method of fitting autoregressive-moving-average ://   A Review and Comparison of Methods for Detecting Outliers in Univariate Data Sets Songwon Seo, M.S. cases are good examples of outlier analysis in terms of the second aspect of an outlier: 1) to identify medical practitioners who under- or over-utilize specific procedures or The first book to discuss robust aspects of nonlinear regressionwith applications using R software Robust Nonlinear Regression: with Applications using R covers a variety of theories and applications of nonlinear robust regression.

Typically the observations can be over an entire interval, randomly sampled on an interval or at xed time points. Di erent types of time sampling require di erent approaches to the data ://~suhasini/teaching/ Section 6 discusses problems of robust nonlinearity tests in time series, and robust estimation in some non-linear time series models.

The basic ingredients of the FS are a robust start from an outlier-free subset of observations, a criterion for progressing in the search, which allows the subset to increase by one or more observations at each step, and a set of diagnostic tools that are In Fotopoulos and Ahn (J Time Ser Anal 24(6): –, ), these unit root rank tests were analytically and empirically investigated and compared to the DF test, but with outlier-free processes.
