Table DOT0. z (Gaussian/Normal) distribution

See nQuery Advisor® manual Appendix for computing method. Figure DOT0 shows the two most commonly used z-value computations. Range of values tested: probability .0005, .001, .01, .5, .99, .999, .9995 to z, and corresponding values of z back to probability. Values checked against tables in Dixon WJ, Massey FJ (1983) Introduction to Statistical Analysis. 4th edition. McGraw-Hill. New York and/or StaTable. Electronic Tables for Scientists and Engineers. Version 1. 1994 Cytel Software Corporation.

Figure DOT0. In the first two columns, nQuery Advisor® 7.0 solved for z_p; in the last two columns, nQuery Advisor® 7.0 solved for probability.
