Distribution

You can set specification limits using the Spec Limits column property or using the Spec Limits argument in JSL:

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

dt << Distribution(

Column( :OZONE ),

Fit Distribution(

Weibull(

Spec Limits( LSL( 0.075 ), Target( 0.15 ), USL( 0.25 ) )

)

);

To set specification limits using K Sigma normal probabilities, use the Set Spec Limits for KSigma message. The first argument to the message is the value of K Sigma. By default, the limits are two-sided. To make them one-sided, use the optional sided argument. Specify sided=1 for LSL only and sided=2 for USL only.

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

obj = Distribution( Column( :CO ) );

obj << Fit Distribution(

LogNormal( Set Spec Limits for KSigma( 3 ) )

);
