SUPPORTED STATISTICS

This section provides a list of the statistics that are currently available in Dataplot.

The calculation of individual statistics is done via subcommands under the LET command, as in

    LET A = MEAN X
    LET B = STANDARD DEVIATION Y
    LET C = CORRELATION X Y

Statistics are computed on either one, two, or threee response variables (never parameters or functions) and the computed statistic is always stored in a parameter (never a variable or function). The 2011/6 version added support for matrix arguments on the right hand side of the equal sign.

The usefulness of these built-in statistics is increased by the fact that these statistics can be used in the following commands:

  1. LET A = <stat>
  2. <stat> STATISTIC PLOT
  3. <stat> CUMULATIVE STATISTIC PLOT
  4. <stat> MOVING STATISTIC PLOT
  5. <stat> WINDOW STATISTIC PLOT
  6. CROSS TABULATE <stat> STATISTIC PLOT
  7. FLUCTUATION PLOT <stat>
  8. TABULATION PLOT <stat>
  9. <stat> BLOCK PLOT
  10. BOOTSTRAP <stat> PLOT
  11. JACKNIFE <stat> PLOT
  12. DEX <stat> PLOT
  13. <stat> INFLUENCE CURVE
  14. CROSS TABULATE <stat>
  15. POSITIONAL TABULATE <stat>
  16. LET V = MATRIX COLUMN <stat>
  17. LET V = MATRIX ROW <stat>
  18. LET A = MATRIX GRAND <stat>
  19. LET M = MATRIX PARTITION <stat>
  20. LET M = GENERATE MATRIX <stat>
  21. LET V = CROSS TABULATE <stat>
  22. LET V = CROSS TABULATE CUMULATIVE <stat>
  23. LET V = SORT BY <stat>
  24. LET V = MOVING <stat>
  25. LET V = CUMULATIVE <stat>
  26. LET V = WINDOW <stat>

When new statistics are added to Dataplot, they will be listed here rather than in the separate documentation for each of the above commands.

Some of the above commands only support the case where the statistic is computed from a single response variable.

The available statistical subcommands are (for the specifics of a given statistic, enter HELP <stat> where <stat> denotes one of the statistics given here)--
