MS-Excel-Tools (ACOMED statistik)

ACOMED statistik is providing statistical services - mainly in the field of diagnostic studies, evaluation of diagnostic tests, ROC analyses and so on. Although commercial statistical software is used in my company usually, it is advantegeous to use MS Excel-tools in some cases, for instance if free layout of the figures is required. Free demo versions with restricted numbers of cases are available (single ROC curve, comparison of two ROC curves).

Providing statistical services is the core subject of ACOMED statistik's business. However, 3 MS Excel tools related to ROC curves and DAC-method have been developed. Beside the advantages in free layout of figures, the ACOMED - tools are more comfortable in terms of group selection and combination, because in commercial software a transformation to the groups 0 and 1 has often to be performed before starting the analyses.

You can purchase the tools in ACOMED's webshop paying only the cost price (23 EUR: single ROC-curve .. 49 EUR: package of 2 tools). The tool calculating the DAC method is available when the method is published (march 2005 in Clinical Chemistry).
