Dear all,

I'm triyng to add a goodness of fit after a distribution, using a script. There is a loop. The analysis is performed for n columns.

this is the part of the code:

disti = dt << Distribution( stack( 0 ), Continuous Distribution( Column( listName[i] )), Normal Quantile Plot( 1 ), Fit Distribution( Normal(Goodness of Fit( 1 ) )), Capability Analysis( 1 ), Invisible( 1 ) );

But no goodness of fit appears... and I don't konw why..

Do you have an idea?

What does it mean the "1" parameter of this function?

Thank you

Maïna

Solution

I have expanded your script slightly, to make it a functioning script. Your code works well using the Semiconductor Capability data table. I suggest that you look at the makeup of your data or the list, "listName".

```
Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA\semiconductor capability.jmp" );
listName = dt << get column names( numeric, continuous );
For( i = 1, i <= 2, i++,
disti = dt << Distribution(
stack( 0 ),
Continuous Distribution( Column( listName[i] ) ),
Normal Quantile Plot( 1 ),
Fit Distribution( Normal( Goodness of Fit( 1 ) ) ),
Capability Analysis( 1 ),
Invisible( 1 )
)
);
```

Thank you Jim,

I have already do this loop :) IThe script is bigger !

My first script was like that:

The distribution appears, the capability analysis too, but not the goodness of fit test...

I don't understand why ;(

```
disti = dt << Distribution(
stack( 0 ),
Continuous Distribution( Column( listName[i] ) ),
Normal Quantile Plot( 1 ),
Capability Analysis( 1 ),
Invisible( 1 )
```

But I want to add a goodness of fit analysis below the histogram of the distribution.

Tks

I used your script, and just attached a different data table, so that is why I suggested that you need to look elsewhere.

Or do I have no place to display the result?

Would that be possible?

Are the columns you are analyzing of Modeling Type Continuous? If they are Ordinal or Nominal, they will not provide a goodness of fit
