- 1. GENERAL DESCRIPTION
-
- STATRCOR (Ver 1.5)
-
- STATistics: Ranks and CORrelations is part of the interactive statistical
- system by Timo Salmi. It is the fourth program in the set. The first program
- in the set is Statistical measures (STATMEAS in TS1STxx.ARC), which is
- intended for univariate analysis. The second program in the set is multiple
- regression analysis (STATREGR in TS2STxx.ARC). The third program in the set
- is for transforming observations (STATTRAN in TS3STxx.ARC). The fifth program
- in the set is STATistics: Least Absolute Deviation multiple Regression
- (STATLADR in TS5STxx.ARC).
- STATRCOR includes a built-in help system, which can be invoked by typing ?
- at any interactive question. Because of this built-in help, and the
- interactive nature of the program's user interface, no long-winding
- instructions have been included. (Who reads instructions anyhow?)
- STATRCOR optionally calculates:
- 1) The ordinary Pearson's correlation coefficients
- 2) The t-test values of Pearson's correlation coefficients for testing
- their statistical significance
- 3) Spearman''s rank correlation coefficients
- 4) Ranks of the observations for any individual variable.
-
- More information about the required format of the input data, and other
- details, can be found in the documentations of the earlier programs in this
- statistics set. The information is not repeated here.

- 2. RELEASE NOTES
-
- Version 1.1: Some internal changes.
-
- Version 1.2: Some of the routines of the Turbo Pascal code have been
- optimized for increased speed.
-
- Version 1.3: This version introduces input recall and line editing. The
- special keys Del, CrLf, CrRg, CrUp, Home, End, and Esc are functional for
- this purpose. PgUp is the recall key. Line editing uses insert mode.
- Disk access has been made faster (the program has its own cache).
- The directory routine has been updated.
- Read-only files can be read properly.
-
- Version 1.4: While fixing a bug in the multiple regression program I also
- made some enhancements in the routines which are common to all my statistical
- programs. Most importantly the insert key has been made functional in the
- line editing.
-
- Version 1.5: The line editing potential of the program has been improved.
- When the task is given from the keyboard, and continuation lines are used,
- the repeated input recall (CursorUp) gets each line in turn. Ctlr-C and
- break-key abort have been enhanced.
- A line can be continued using an &, or a * at the end. Now also the
- backslash \ is accepted. This was suggested by Tuomas Eerola.
- Some help texts within the program have been extended.
-
- Version 1.6: Several improvements to the nuts and bolts of the user
- interface.
- The new usage of the call is
- PROGNAME [/h(elp)] [/iInputFileName] [/oOutputFileName] [/cColumnsPerRow]
- (the /c option, which regulates the width of the output, is for registered
- versions, only). If you use the /i switch, it stuffs the InputFileName into
- the appropriate recall buffer. This means that when the program asks you for
- the input file name, you can invoke the input file name just by pressing the
- CursorUp key. (The same goes for the /o switch, respectively.) This is very
- convenient, if you use the program many times successively making small
- changes in your data in between. (This assumes, of course, that you have a
- command line editor like DOSEDIT or CED to recall previous MsDos commands.
- These common shareware programs can be obtained from any well-stocked BBS or
- FTP site.)
- The printer readiness test has been rewritten to be more general. The
- earlier test failed for some printers, because the codes the printers send
- when they are offline are not standardized.
- The "file exists, overwrite?" question is no more asked when the output
- file is prn, in other words when the output is directed to the printer.
- The user has now a choice of a left margin from 0 to 20 blanks when output
- is directed to the printer.
- The user has now a choice between formfeed and four blank lines to start
- each new page of output.
- When an input file is not found, the user is given the choice of listing a
- directory. The directory routine has been rewritten.
- The file ready message now also includes the file side besides the name.
