Process Variables

The columns of process data containing the measurements to be analyzed. The columns must have a Numeric data type. If a process variable has a Control Limits column property, the Process Screening platform uses those limits to calculate the Specified Sigma.

Note: The platform does not support control limits that are specified in a Control Limits column property for dispersion (R) charts.

Grouping

Columns assigned as grouping variables. Each process variable is analyzed at each combination of levels of the grouping variables. The results are presented in a single report.

Subgroup

A column whose values assign a subgroup identifier to each row. The process data are sorted by the Subgroup variable before calculations are performed.

Time

A numeric column whose values are used for the time order for the data. Use the Time role for data that are time-stamped. The time stamp is used for the time axis in quick graphs and shift graphs. The process data are sorted by the Time variable before calculations are performed.

By

A column whose levels define separate analyses. For each level of the specified column, the corresponding rows are analyzed using the other variables that you have specified. The results are presented in separate tables and reports. If more than one By variable is assigned, a separate analysis is produced for each possible combination of the levels of the By variables.
