scripting t-test: picking favorite features from several ANOVA/t-tests; 2-sample vs 3+-sample?

So curious how to make this happen. I've got a long list of charts, some with 2 chambers, some with 3+ chambers. I'd like to script a t-test kind of script to standardize the output. Any advice? There's parts and pieces I like from several different options.

 

Goal:

- output a chart w/ student's t Circle Plots

- output a 'summary report' with sample count, mean, stDev

- output a p-value for the whole chart (Means/Anova/Pooled t")

- (nice to have: pair-wise p-value and labeling, but not that important).

 

I've noticed that the options and outputs are quite different if I have a 2-sample chart vs a 3+sample chart.

 

Any advice how to script this?

If you have an easy way to check the number of levels, you can use an IF() to check and bypass the statement.  Or, you can use a TRY() function to keep it from ending when the statement fails

try(report(ow[i])["Oneway Anova"]["Pooled t Test"] << visibility("Collapse"));

Re: scripting t-test: picking favorite features from several ANOVA/t-tests; 2-sample vs 3+-sample?

Edit/Update.

So I setup some JSL and edited as much as I can figure, but still hitting a roadblock. I can't seem to collapse/hide Student t Test subwindows.

 

Is there a BKM for simply outputting the YbyX chart, circles, histogram on upper level and then "Analysis of Variance, Summary, and Ordered Difference Report on lower level?

Re: scripting t-test: picking favorite features from several ANOVA/t-tests; 2-sample vs 3+-sample?

Because you are using a By() clause, the output report is actually a separate report for each level of the By().  Here is how I handle what you are asking for.  My example is probably not exactly what you want, but it should move you in the correct direction.

by.PNG

names default to here(1);
dt=open("$sample_data/big class.jmp");
//dt<<color by column(:sex);
ow = Oneway(
	Y( :height ),
	X( :sex ),
	by(:age),
	Box Plots( 1 ),Means( 1 ), //means/anova/pooled t
	Each Pair( //student's t-Test
		1,
		Difference Matrix( 0 ),
		Confidence Quantile( 0 ),
		LSD Threshold Matrix( 0 ),
		Connecting Letters Report( 0 ),
		Ordered Differences Report( 1 ),
		Detailed Comparisons Report( 0 )
	),
	Points Jittered( 1 ),
		Box Plots( 1 ),
		Mean Diamonds( 0 ),
		Mean Error Bars( 0 ),
		Std Dev Lines( 0 ),
		Grand Mean( 0 ),
		SendToReport(
		//x-axis formatting
		Dispatch(
			{},
			"2",
			ScaleBox,
			{Label Row(
				{Label Orientation( "Angled" ), Lower Frame( 1 ),
				Show Major Grid( 1 ), Tick Mark Style( "Long Divider" )}
				)
			}
		),
		//row legend by chamber
		Dispatch(
			{},
			"Oneway Plot",
			FrameBox,
			{Marker Size( 6 ), Marker Drawing Mode( "Normal" ),
			Row Legend(
				:TOOL_PROCESS_CHAMBER,
				Color( 1 ),
				Color Theme( "JMP Default" ),
				Marker( 0 ),
				Marker Theme( "" ),
				Continuous Scale( 0 ),
				Reverse Scale( 0 ),
				Excluded Rows( 0 )
				)
			}
		)
	));

ow << histograms(1);
For(i=1,i<=nitems(ow),i++,
	report(ow[i])["Oneway Anova"]["Summary of Fit"] << visibility("Collapse");
	report(ow[i])["Oneway Anova"]["Pooled t Test"] << visibility("Collapse");
	report(ow[i])["Oneway Anova"]["Means for Oneway Anova"] << visibility("Collapse");
	report(ow[i])["Means Comparisons"] << visibility("Collapse");
)

Re: scripting t-test: picking favorite features from several ANOVA/t-tests; 2-sample vs 3+-sample?

Thank you. This is kinda working. One problem is that a graph with 3+ chambers does not have a Pooled t Test section, then it errors out and stops. 

 

How to move past to next row while still staying in its i iteration?
