Description: Returns the results of the Common Beta Hypothesis (CBH) goodness-of-fit test. This function is applicable to the following data types:
Times-to-failure data
Multiple Systems - Concurrent Operating Times
Multiple Systems with Dates
Multiple Systems with Event Codes
Fielded data
Repairable Systems
Fleet
Syntax: COMMONBETAGOF (Data_Src, Value_Index, Signif_Level)
Data_Src is the source data sheet from which the value is calculated.
Value_Index is a numerical value that allows you to specify which result to display:
To show whether the test passed or failed = 0.
To return the lower test value = 1.
To return the critical value = 2.
To return the upper test value = 3.
Signif_Level is the significance level for the results.
Remarks:
The Data_Src can be one of the following values:
If using a default data source, it must be either 1, 2, 3 or 4, as selected from the Data Source Index drop-down list.
It can take a data sheet name (e.g., "Folio1!Data 1").
It can take a variable name defined in the Defined Names window (e.g., datasource).
If the critical value is between the lower and upper test values, then the CBH test passes.
Example:
COMMONBETAGOF (“Folio1!Data 1”,3,0.1) = 4.605171204
Note that this value will vary depending on the source data set.
