I am running JMP 17 on Windows and it appears that the Odds Ratio order is dependent upon the Alphabetic order of the data. Data whose values of the Y variable were "No" and "Yes" was calculated "Yes vs. No". The same data, with the data changed to "2No" and "1Yes" was calculated "2No vs. 1Yes"
I ran the JSL from the Statistics Index example for Odds Ratios, just changing the values for the Sex column in the Big Class data table from "F" to "Yes" and then to "1Yes" and for "M" to "no" and then to "2No"
Names Default To Here( 1 );
Open( "$SAMPLE_DATA/Big Class.jmp" );
Fit Model(
Y( :sex ),
Effects( :height ),
Personality( "Nominal Logistic" ),
Run( Odds Ratios( 1 ) )
);
