I'd imagine that you could adapt (or even adopt) -nruns- to your purpose. SJ-6-4 st0044_1 . . . . . . . . . . . . Software update for nruns and nrunsi (help nruns, nrunsi if installed) . . . . . . N. Smeeton and N. J. Cox Q4/06 SJ 6(4):597 introduces commands nruns and nrunsi for analyzing sequences stored in a variable or supplied on the fly SJ-3-3 st0044 Do-it-yourself shuffling & the number of runs under randomness . . . . . . . . . . . . . . . . . . . . . . . N. Smeeton and N. J. Cox Q3/03 SJ 3(3):270--277 (no commands) explains estimation of the probability of an event under randomness; illustrates a simple method of random shuffling; and shows derivation of conditional probability distribution of the number of runs Nick n.j.cox@durham.ac.uk Richard Goldstein Thanks, but Nope -- this is a one-sample test such as one might use for residuals -- it compares runs against some threshhold -- the W-W test is a two sample test Ronan Conroy wrote: > On 16 Noll 2009, at 15:03, Richard Goldstein wrote: > >> does anyone know of a program to perform the Wald-Wolfowitz runs test >> (Wald, A and Wolfowitz, J (1940), "On a test of whether two samples are >> from the same population," _Annals of Mathematical Statistics_, 11: >> 147-162)?
