A new WIN32 computer program for estimating immunoassay variance functions.
A new WIN32 computer program for estimating immunoassay variance functions is described. It replaces and enhances an MS-DOS version written more than a decade ago. Input data can consist of either runs of raw replicated measurements (maximum: 40,000 observations) or sets of values of N, mean and SD (maximum: 20,000 sets). Data can be imported from Paradox, dBase, Foxpro or Access database tables, from text files, or via the Windows clipboard. The program produces histogram plots of sets of replicates and plots containing up to 12 variance functions expressed in terms of variance, SD or CV(%) versus the mean (imprecision profiles). Any specified view of a variance function graph can be inset into any other view. Interactive point and click design dialogues give virtually complete control over graph appearance. Graphs can be exported to external applications via the clipboard or disk files, in either bitmap or Windows enhanced metafile format.
