title: Fitting multi-parameter distributions to sister chromatid exchange data.
abstract: Bender et al. (1992) presented the number of sister chromatid exchanges (SCE) in 50 peripheral blood lymphocytes from each of 393 normal human subjects. In that study of 19650 cells, the number of SCE per cell ranged from 0 to 32. We examine the resulting frequency distributions, and show how they may be fitted, by the method of moments, to discrete Pearson-type and Johnson translation system distributions.
