Fit Normal() - Differences of parameter estimates standard error and confidence intervals between versions (JMP 16 vs JMP 18.2)

[#1]

Hi,

I noticed some numerical differences between JMP versions, and I was wondering what has changed in the computation of the standard errors and confidence intervals of the parameters estimates of Fit Normal() from JMP 16 to the next versions?

It would be great if you can specify any difference in formulas and methods between the two versions.

The following output has been produced by using the same data and running the following chunk of code in JMP 16.0 (left) and JMP 18.2 (right). 

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
obj = dt << Distribution( Column( :Weight ) );
obj << Fit Normal;

Thanks in advance to anyone who replies!

Hi,

Could you highlight which parameters do not match between the two outputs you shared? I scanned the table for differences, but I could not detect any.

Thanks,
