    • Women in theoretical statistics
  • Gertude Cox and Janet Norwood, the two women described in this chapter, were primaly administrators and teachers. Women also played an important role in the development of theoretical statistics in the later half of the twentieth century. Recall L.H.C. Tippett's first asymptote of the extreme that is used to predict ``hundred-year floods,'' as described in chapter 6. A version of that distribution, known as a ``Weibull distribution,'' has found important uses in the aerospace industry. One problem with the Weibull distribution is that it does not meet Fisher's regularity conditions, and there are no clearly optimal ways of estimating its parameters. That is, there were no optimal ways until Nancy Mann at North American Rockwell discovered a link between a much simpler distribution, and developed the methods now used in that field.
  • Since the days of Snedecor and Cox, the ``best person'' has frequently been a woman.
