How can I segregate my data
In Weibull++, you can use the Batch
Auto Run tool to extract subsets of your data into new data sheets for separate
To use the tool, you will first need to define a subset ID for
each data point you want to extract, making sure that the data points you wish to group
together all have the same ID. For example, the following data sheet contains failure
times for a product that was manufactured in two different plants. The Subset ID
column identifies the facility that manufactured each failed unit.
If you wish the analyze the data for each plant separately,
choose Data > Batch Auto Run or click the icon that appears on the Main
tab of the standard folio’s control panel and on the Data Analysis toolbar.
When the utility opens, you will see a list of all the subset IDs
that are available to be extracted and a list of those that have already been selected. To
select one or more subsets, you can a) click and drag the ID from one column to the other,
b) double-click the ID or c) use the Select All Available or Clear All
Selected buttons below the columns. The following picture shows the tool with both
subset IDs selected for extraction into separate data sheets.
The Set Action Preferences for Processing tab provides
some calculation and naming options for the new data sheet(s) that will be created. For
this example, we have selected the option to automatically calculate the parameters for
each new data sheet, as shown next. When you click OK to create the new data
sheets, the parameters will be calculated based on the distribution that was selected
in the original data sheet.
NOTE: There’s another feature in Weibull++ called
"Specify Points" that has a similar interface but a different purpose. As seen
in this example, the Batch Auto Run tool creates separate data sets so you can analyze
them separately. Alternatively, the Specify Points tool allows you to mark specific
points within a single data sheet as "outliers" in order to give them special
treatment in a rank regression analysis. For more information about this feature,
What resources are available
to help me learn to use ReliaSoft’s software tools?
At ReliaSoft, we understand how important it is for users
to "hit the ground running" when they install a new software tool. Therefore,
