Fit Life by X，Devalt.jmp，Parameter correlation

Jul 5, 2025 10:46 PM (284 views)

The JMP sample data file "Devalt.jmp" is included with the software. If you select the Weibull distribution" and perform the analysis using "Fit Life by X", the correlation between β0 and β1 in the results is -0.999188, indicating a very strong correlation. Is this acceptable? What impact does it have on the results, and is it significant?

How can the robustness of this predictive model be evaluated?
