Fatigue Model

Summary: Creates and analyzes a fatigue model, generating estimates, reports, and fitting information for a data table.

Code:

dt = Open("data_table.jmp");
obj = dt << Fatigue Model(
    N( :Cycles ),
    S( :Stress ),
    Censor( :Censoring Indicator ),
    Censor Code( "Runout" ),
    Fit Model( "Box-Cox Loglinear Sigma", "Lognormal" )
);
getEst = obj << get estimates;
rpt = obj << report;
fitInfo = obj << get fitting information();
scales = ((fitInfo << get values)[1]) << get values;
modCompEst = (rpt[Outline Box( "Model Comparisons" )][Table Box( 1 )] << get as matrix);
modCompTxt = (rpt[Outline Box( "Model Comparisons" )][Text Box( 1 )] << get text);

Code Explanation:

1. Open data table;
2. Create Fatigue Model object.
3. Set cycles as N.
4. Set stress as S.
5. Set censoring indicator.
6. Define censor code as "Runout".
7. Fit models: Box-Cox Loglinear Sigma, Lognormal.
8. Retrieve estimates.
9. Generate report.
10. Get fitting information.
