URBAN TRAVEL DEMAND FORECASTING PROJECT, FINAL REPORT SERIES, VOLUME IV: QUAIL 4.0 USER'S MANUAL

Instructions for using the QUAIL special computer program are detailed. QUAIL is the acronymn for Qualitative, Intermittent, and Limited Dependent Variable Statistical Proram employed to analyze statistical models involving non-continuous dependent variables and to manipulate storage of associated arrays of data. QUAIL is written is Fortran IV and is designed so that most errors in command statements are detected before data is recorded or results are compiled. Running a QUAIL program involves two steps--The QUAIL compiler scans the program for syntax errors and also creates a list of variables used but not created by the program; and the interpreter performs indicated operations, automatically loading any needed permanent variables from QUAIL tape or disk files. The manual describes selection of subsamples, the IDCASE/IDALT structure, manipulation of variables, input and output of variables, QUAIL files, stop, end, list, MACROS in QUAIL, advanced features in DIMEN and SMPL, logit estimation, other statistical procedures, matrix operations and QUAIL statements.
