Data from R.A. Fisher, 1936, on the characteristics of 50 iris flowers of three species: iris setosa, iris versicolor and iris virginica. Four characteristics are recorded for each flower: sepal length, sepal width, petal width, and petal length.

We present an econometric analysis of wage behaviour in Norway during the interwar years. The analysis is based on a panel of manufacturing industry data using GMM estimation methods. Our empirical analysis shows that wage formation in the interwar period can be understood with the help of...

We present a new procedure for detecting multiple additive outliers in GARCH(1,1) models at unknown dates. The outlier candidates are the observations with the largest standardized residual. First, a likelihood-ratio based test determines the presence and timing of an outlier. Next, a second...

This paper discusses and documents the algorithms of SsfPack 2.2. SsfPack is a suite of C routines for carrying out computations involving the statistical analysis of univariate and multivariate models in state space form. The emphasis is on documenting the link we have made to the Ox computing...

We investigate several aspects of GARCH(p,q) models which are relevant for empirical applications. In particular, we note that the inclusion of a dummy variable as regressor can lead to multimodality in the GARCH likelihood. This makes standard inference on the estimated coefficient impossible....

We suggest a convenient version of the omnibus test for normality, using skewness and kurtosis based on Shenton and Bowman ["Journal of the American Statistical Association" (1977) Vol. 72, pp. 206-211], which controls well for size, for samples as low as 10 observations. A multivariate version...
