Required Arguments NI — Vector of length NGROUP containing the number of observations in each mean. (Input) YMEANS — Vector of length NGROUP containing the means. (Input) DFS2 — Degrees of freedom for s 2 . (Input) S2 s 2 , the estimated variance of an observation. (Input) The variance of YMEANS ( I ) is estimated by S2 / NI ( I ). STAT NGROUP * ( NGROUP 1)/2 by 5 matrix containing the statistics relating to the difference of means. (Output) Col. Description 1 Group number for the i -th mean 2 Group number for the j -th mean 3 Difference of means ( i -th mean) ( j -th mean) 4 Lower confidence limit for the difference 5 Upper confidence limit for the difference Optional Arguments NGROUP — Number of means. (Input) Default: NGROUP = size ( NI ,1). IMETH — Method used for constructing confidence intervals on all pairwise differences of means. (Input) Default: IMETH = 0. IMETH Method 0 Tukey (if equal group sizes), Tukey-Kramer method (otherwise) 1 Dunn-Sidak method 2 Bonferroni method 3 Scheffe method 4 One-at-a-time t method LSD test CONPER — Confidence percentage for the simultaneous interval estimation. (Input) Default: CONPER = 95.0. IMETH CONPER 0 Percentage must be greater than or equal to 90.0 and less than or equal to 99.0. 1 Percentage must be greater than or equal to 0.0 and less than 100.0. IPRINT — Printing option. (Input) Default: IPRINT = 0. IPRINT Action 0 No printing is performed. 1 Printing is performed. LDSTAT — Leading dimension of STAT exactly as specified in the dimension statement in the calling program. (Input)

SCIPM http://www.vni.com/products/imsl/documentation/fort06/stat/NetHelp/s. .. 2 of 5 11/8/2007 5:43 AM Default: LDSTAT = size ( STAT ,1). FORTRAN 90 Interface Generic: CALL SCIPM (NI , YMEANS , DFS2 , S2 , STAT [,…]) Specific: The specific interface names are S_SCIPM and D_SCIPM . FORTRAN 77 Interface Single: CALL SCIPM (NGROUP , NI , YMEANS , DFS2 , S2 , IMETH , CONPER , IPRINT , STAT , LDSTAT) Double: The double precision name is DSCIPM . Description Routine SCIPM computes simultaneous confidence intervals on all k * = k ( k 1)/2 pairwise comparisons of k means μ 1 , μ 2 , , μ k the one-way analysis of variance model. Any of several methods can be chosen. A good review of these methods is given by Stolin (1981). Also the methods are discussed in many elementary statistics texts, e.g., Kirk (1982, pages 114
