Regression Report
Reports > Regression Report
See also: |
Use to generate a Statistical Process Control (SPC) Regression report to determine the interdependency between two variables. Up to three dependent variables (y-axis) may be plotted against a single independent variable (x-axis). The degree of correlation between the variables is also reported.
Field or Button | Description | ||||
---|---|---|---|---|---|
Autoscale [check box] | When enabled, allows the x- and y-axes to be scaled automatically. | ||||
Axis Range [text box] | Enter the beginning and ending values for the x- and y-axis ranges. These fields are disabled if Autoscale is selected. | ||||
Label data [check box] | Use to label the points on the plot to correspond with the values in the sample files. | ||||
Recalculate archived SPC results [check box] | Use to have archived SPC values recalculated ensuring any changes made to the SPC Report Options are included in the new report. This option lengthens the time required to generate the report.
When this option is selected, this message will display: Saving the recalculated SPC data may render some files unreadable by the original application. Saving the SPC data speeds up future SPC reports.
The first time this option is used, the time it takes to generate the report is lengthened. The second time the report is generated, if using the same sample files used in the initial calculation, it is recommended that this option not be selected since the data was recalculated previously. If a sample file is added or removed from the report after the initial recalculation, this option should be selected again to ensure the data from the newly added or removed sample file is recalculated. |
||||
Samples [button] | Select additional sample files to add to the report. | ||||
Save as Default [button] | Click to save selected report options as default report settings. | ||||
Show graphic [check box] |
Use to show a graphic on the report header. Height / Width. Enter the height and width of the selected graphic. These values determine the graphic appearance on the generated report. |
||||
Show report title [check box] |
Select and enter a report title to appear on the report header. | ||||
Tabular report [check box] |
Generates a tabular report of the included samples. A tabular report contains the numeric values contributed by each sample. | ||||
X- and Y-Axis Variable [drop‑down box] |
Use to designate the x- and y-axes variables. The variables in the drop-down lists are those selected in the Reports > SPC Report Options window. Use these options to plot the regression of up to three y-axis variables against the x-axis variable. | ||||
