The MSA Factors outline defaults to a 3-part study.
Note: The MSA designer requires at least one factor with a part role.
Add Factor
Click to add one or more factors.
Remove
Removes the selected factors.
Add N Factors
Adds multiple factors. Enter the number of factors to add and click Add Factor.
Show Levels
Select to show factor levels. When selected, the following options are available.
Name
Factor name with a menu to add a level.
Role
Fixed to a categorical factor. MSA factors are categorical by default.
Values
Specifies the factor levels, which you can click to edit.
Name
Specifies the name of the factor, which you can click to edit. Initially, three factors are in the factor list; Operator, Part, and Gauge. You can add or remove factors from this list.
MSA Role
Specifies the MSA Role of the factor. Click to select from Operator, Part, Gauge, or None.
# of Levels
Specifies the number of levels for a factor.
Variance
Specifies a prior variance due to the factor. The default is one, which results in diagnostics that are scaled to the true variability.
Randomize
Specifies to randomize the factor in the design table.
Number of Replicates
Specifies the number of replicates between 0 and 10 to include in your design. The number of replicates is the number of measurements in addition to an initial measurement. The default is two replicates, which results in three measurements for each run. To specify a single measurement per run, set the number of replicates to zero.
Replicate Runs
Specifies the run order for replicate runs in the experiment.
Fast Repeat
replicates are run sequentially.
Batch Repeat
The factor combinations are run in batches. Each replicate set makes up a new batch of runs. The order of runs is the same from batch to batch.
Completely Randomized
the factor combinations are run in batches. Each replicate set makes up a new batch of runs. The order of runs is randomized within each batch.
Note: A Replicates column is included in the final design table. For the completely randomized run option, the Replicates column is hidden.
