Abstract
Quesenberry and Hurst (1964), Goodman (1965) and Fitzpatrick and Scott (1987) proposed simultaneous construction of confidence intervals for multinomial proportions, however, statistical computing packages do n ot generally give one the option of specifying the type of constructio n to be used, We have written a SAS macro using PROC IML that takes mu ltinomial cell counts as input and returns simultaneous confidence int ervals with the user-specified coverage probability. Two main features of the macro are its ease of use and its flexibility in allowing the user to choose among six methods of constructing confidence intervals for multinomial proportions. Based on simulation May and Johnson (1997 ) recommended the intervals proposed by Goodman (1965) in most practic al applications. (C) 1997 Elsevier Science Inland Ltd.
