For Loop every two columns to perform the same function in a data table with n columns

etmsni — Fri, 09 Jun 2023 22:07:21 GMT

Hi! I'm new to JSL scripting, and have tried to read the JSL reference manual/google JSL script examples. Could someone please point me in the direction on how to for loop every two columns to perform the same function in a JMP data table with n columns?

Basically I have a large data spreadsheet where every odd column is failure time, every even column is the censoring, and I would like to fit these data sets automatically n times. I know that if there was only two columns, I can click through the entire process on the JMP GUI interface and grab the script, but I'm not sure how to automate it to repeat the process again.

Thank you!

Here is a simple example of repeating over a data table, 2 columns at a time

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA\semiconductor capability.jmp" );

colNamesList = dt << get column names( continuous, string );

For( i = 1, i <= N Items( colNamesList ), i = i + 2,
	Bivariate(
		Y( colNamesList[i] ),
		X( colNamesList[i + 1] ),
		Fit Line( {Line Color( "Medium Dark Red" )} )
	)
);
