This collection of statistical software components is written in Visual Basic for Applications (VBA). Internal and external databases are accessed from the Excel environment. ClusCorr98 runs under Microsoft Windows. An overview over a new release of the statistical software ClusCorr98 will be given. The emphasis of this software lies on an extended collection of exploratory and model-based clustering techniques with in-built validation via resampling. Using special weights of observations leads to well-known resampling techniques. By doing so, the appropriate number of clusters can be validated. As an illustration of an interesting feature of ClusCorr98, a general validation of results of hierarchical clustering based on the adjusted Rand index is recommended. It is applied to demographical data from economics. Here the stability of each cluster can be assessed additionally.
