Tolerance Intervals for Regression

Feb 15, 2012 3:26 AM

Hi JMP-Users,

im looking for tolerance intervals for simple linear regressions.

I think there is no such function in JMP9Pro, is it? I can only find confidence intervals and prediction intervals in the bivariate plattform.

Maybe some got a script or addin for tolerance intervals?

Thanks in advance!

Tolerance Intervals for Regression

Hi:

Perhaps:

dt = Open("$SAMPLE_DATA/RELIABILITY/Resistor.jmp");

dt << Distribution(

Continuous Distribution(

Column( : Percent Increase ), // note ":" and "P" in Percent Increase should be not separated by a space

Tolerance Interval( Alpha( 0.95 ), Proportion( 0.9 ) )

)

);

Best regards,

-Matt

Tolerance Intervals for Regression

Thanks for the answer but sadly thats not what i need.

Im looking for, well .. tolerance bands around a regression line.

Sorry if my question was misleading.

Re: Tolerance Intervals for Regression

Well i found an R package and converted the code for JMP (as i dont want to use the R-JMP Interface).

Its just for simple linear regression, but better than nothing. :-)

Re: Tolerance Intervals for Regression

If it is a regression model with more than one predictor, then does Save Columns > Indiv Confidence Limit Formula from the Fit Model hot spot give what you are after? Both Graph Builder and Bivariate will give you equivalent prediction intervals in the case of modeling one continuous predictor on one continuous response.
