HIST: Histogram

The HIST record controls which standardized residual histograms are printed. This option has no effect on the performance of the histogram viewer in GeoLab. To produce a histogram you place HIST records in the proper places in your input text file (see further instructions below).

The format of the HIST record is as follows:

Columns 002-005: HIST
Columns 007-009: NEW, GEN, ALL, or END (see below).
Columns 011-074: Histogram title (any text)

The NEW option clears the histogram (if necessary) and starts building a new histogram with observations following the HIST record. The histogram title field is not used for the NEW option. The GEN option generates (prints) a histogram based on the observations after the last NEW record. The title is used by the GEN option to specify the printed title of the generated histogram. The ALL option results in printing the histogram for all observations up to the location of the ALL record. The END option can be used anywhere in your input file, and produces the same result as an ALL option placed after all observation records. The title is used by the ALL option to specify the printed title of the generated histogram. Note that the use of the ALL option is independent of the NEW/GEN pairings and can be used anywhere in your input text file. Also note that a histogram must contain at least 6 observations (residuals) in order to be printed.
