WebThe Studentized Range Distribution Description. Functions of the distribution of the studentized range, R/s, where R is the range of a standard normal sample and df \times s^2 is independently distributed as chi-squared with df degrees of freedom, see pchisq. Usage ptukey(q, nmeans, df, nranges = 1, lower.tail = TRUE, log.p = FALSE) qtukey(p, … The value of the studentized range, most often represented by the variable q, can be defined based on a random sample x1, ..., xn from the N(0, 1) distribution of numbers, and another random variable s that is independent of all the xi, and νs has a χ distribution with ν degrees of freedom. Then has the Studentized range distribution for n groups and ν degrees of freedom. In applications, th…

http://vassarstats.net/tabs_q.html WebSep 20, 2016 · 1 Answer. The Studentized Range Distribution is a function of q, k, and df, where k is the number of groups of means, and df is the degrees of freedom. If ϕ ( z) is the standard normal PDF, and Φ ( z) is the standard normal CDF: This seems to agree with the tables of critical q values when d f = ∞. However, if I replace the standard normal ... ff20203

WebMay 27, 2003 · This function finds the Tukey's q studentized range critical value. This modified macro is based on the Fortran77 algorithm AS 190.2 Appl. Statist. (1983). It needs the sample degrees of freedom (must be the same for each sample), the k number of samples and the p-cumulative probability value (default=0.95).
