In modelling macroeconomic time series, often a monthly indicator of global real economic activity is used. We propose a new indicator, named World steel production, and compare it to other existing indicators, precisely the Kilian's index of global real economic activity and the index of OECD...

In this article we introduce the Stata command simcadi. It helps to calculate indicators for the similarity of categorically ordered variables and distribution, respectively. In particular, it permits the calculation of the Cosine index, and indices introduced by Finger and Kreinin (1979), Bray...

Data insufficiency and reporting threshold are two main issues in operational risk modelling. When these conditions are present, maximum likelihood estimation (MLE) may produce very poor parameter estimates. In this study, we first investigate four methods to estimate the parameters of truncated...
