This paper offers a visual tour throughout ViSta 6.4, a freeware statistical program based on Lisp-Stat and focused on techniques for statistical visualization (Young 2004). This travel around ViSta is based on screen recordings that illustrate the main features of the program in action. The...

Marsaglia (2003) has described a class of Xorshift random number generators (RNGs) with periods 2^n - 1 for n = 32, 64, etc. We show that the sequences generated by these RNGs are identical to the sequences generated by certain linear feedback shift register (LFSR) generators using "exclusive...

StatCrunch, formerly known as WebStat, is a statistical data analysis software package for the World Wide Web (WWW). After version 1.0 [1] of the software was published as a prototype package in'97, version 2.0 was released in'99 as a fully functional statistical software package. Version 2.0...

The structure, or Hasse, diagram described by Taylor and Hilton (1981, American Statistician) provides a visual display of the relationships between factors for balanced complete experimental designs. Using the Hasse diagram, rules exist for determining the appropriate linear model, ANOVA table,...

This article provides a little table-free C function that evaluates the normal distribution with absolute error less than 8 x 10 ^-16 . A small extension provides relative error near the limit available in double precision: 14 to 16 digits, the limits determined mainly by the computer's ability...
