What it does
- Accepts data from the clipboard, e.g. data you copy from a spreadsheet. The data columns must contain the Operator, Specimen, Replicate, and Measurement. The first three (operator, specimen, and replicate) must be integers. The measurement must be a real number. The sample data file contains an example of the format, and you can use it to try the program. (Do not copy the column labels, copy A2..D121 to reproduce the results in SPC Essentials and Productivity Improvement, pp. 171-172)
- Performs a gage capability study by means of:
- the General Motors long form method (uses sample ranges and control chart factors)
- (other methods may be added later, e.g. Analysis of Variance/ variance components)
- Generates a range chart that shows sample ranges for each operator and specimen.
- For detection of outliers
- The bitmap chart can be saved for copying into reports
- ActiveX page with the program
- Help file for the program (gage_cap.hlp)
- Help file contents (gage_cap.cnt) Download the .hlp and .cnt files to have a Windows Help file with a table of contents
- Sample data in an Excel file (gage_cap.xls, version 5/95 for compatibility with older spreadsheets)
The program has been marked as safe for initialization
and scripting. It writes a file called gage_cap.txt to your hard drive;
this is simply a copy of what you place on the clipboard. It does not write
anything else to your hard drive unless you tell it to, e.g. to save a
chart as a bitmap file.
