Measurement Systems Analysis Platform Options
Platform options appear within the red triangle menu next to Measurement Systems Analysis. Selecting an option creates the respective graph or report in the MSA report window. Deselecting an option removes the graph or report. Choose from the following options:
Average Chart
A plot of the average measurement values for each combination of the part and X variables. The Average Chart helps you detect product variation despite measurement variation. In an Average Chart, out of control data is desirable because it detects part-to-part variation. See Average Chart.
Range Chart
A plot of the variability statistic for each combination of the part and X variables. Appears only if you selected Range as the Chart Dispersion Type in the launch window. The Range Chart helps you check for consistency within subgroups. In a Range Chart, data within limits is desirable, indicating homogeneity in your error. See Range Chart or Standard Deviation Chart.
Std Dev Chart
A plot of the standard deviation statistic for each combination of the part and X variables. Appears only if you selected Standard Deviation as the Chart Dispersion Type in the launch window. The Standard Deviation Chart helps you check for consistency within subgroups. In a Standard Deviation Chart, data within limits is desirable, indicating homogeneity in your error. See Range Chart or Standard Deviation Chart.
Parallelism Plots
An overlay plot that reflects the average measurement values for each part. If the lines are relatively not parallel or crossing, there might be an interaction between the part and X variables.
Tip: Interactions indicate a serious issue that requires further investigation. For example, interactions between parts and operators mean that operators are measuring different parts differently, on average. Therefore, measurement variability is not predictable. This issue requires further investigation to find out why the operators do not have the same pattern or profile over the parts.
EMP Results
a report that computes several statistics to help you assess and classify your measurement system. See EMP Results.
Effective Resolution
a report containing results for the resolution of a measurement system. See Effective Resolution.
Bias Comparison
an Analysis of Means chart for testing if the X variables have different averages. See Bias Comparison.
Test-Retest Error Comparison
an Analysis of Means for Variances or Analysis of Means Ranges chart for testing if any of the groups have different test-retest error levels. See Test-Retest Error Comparison.
Shift Detection Profiler
an interactive set of charts that you can adjust to see the probabilities of getting warnings on your process behavior chart. See Shift Detection Profiler.
Variance Components
a report containing the estimates of the variance components for the given model. The calculations in this report are based on variances, not ranges. Balanced data uses the EMS method. Unbalanced data uses the REML method.
Note: This report is similar to the Variance Components report in the Variability Chart platform, except that it does not compute Bayesian variance component estimates. For more information, see Variance Components in Variability Gauge Charts.
EMP Gauge RR Results
a report that partitions the variability in the measurements into part variation and measurement system variation. The calculations in this report are based on variances, not ranges.
Note: This report is similar to the Gauge R&R report in the Variability Chart platform, except that the calculation for Reproducibility does not include interactions. For more information about Gauge R&R studies, see About the Gauge R&R Method in Variability Gauge Charts.
See Local Data Filter, Redo Menus, and Save Script Menusin the Using JMP book for more information about the following options:
Local Data Filter
Shows or hides the local data filter that enables you to filter the data used in a specific report.
Redo
Contains options that enable you to repeat or relaunch the analysis. In platforms that support the feature, the Automatic Recalc option immediately reflects the changes that you make to the data table in the corresponding report window.
Save Script
Contains options that enable you to save a script that reproduces the report to several destinations.
Save By-Group Script
Contains options that enable you to save a script that reproduces the platform report for all levels of a By variable to several destinations. Available only when a By variable is specified in the launch window.
