  • Estimating and testing with the Bhattacharya plot
    Computational Statistics & Data Analysis, 1991
    Co-Authors: F. G. Boese
    Abstract:

    Abstract Mixtures of subpopulations of biological particles are appropriately described by finite mixture densities. Often, samples drawn from such populations are condensed in the form of histograms. In the exploratory phase of a parametrical data analysis, one wishes to obtain first estimates for the parameters of such mixtures. A parameter of special significance is the number of subpopulations. For the case of univariate normal mixtures, an explanatory graphical device called Bhattacharya Plot is presented. It allows one to obtain the required first estimates and provides assistance in the test of the normality of the mixture. The degree of overlapping in the histogram must not be too severe.

  • Bhattacharya: a new application for quality control.
    Annals of clinical biochemistry, 1991
    Co-Authors: W P Oosterhuis, T A Modderman, R B Dinkelaar, A H Zwinderman, H J Van Der Helm
    Abstract:

    The Bhattacharya method and the 'average of normals' method for internal quality control were compared. Both are based on unselected patient test results. The Bhattacharya method is mostly used in clinical chemistry for calculation of reference intervals but could be modified for quality control procedures. Using the data of a coagulation test and stimulating systematic errors, it was concluded that the Bhattacharya method is more sensitive to expected shifts and is more flexible than the 'average of normals' method.
