Gibt es in JMP eine interaktive Methode, um zu bestimmen, ob sich die Mittelwerte zweier Populationen um mindestens einen bestimmten Betrag unterscheiden, oder allgemeiner, um den p-Wert oder die Wahrscheinlichkeit durch die minimale Differenz der Mittelwerte darzustellen?
Beispiel: Zeigen Sie im Big-Class-Datensatz die Wahrscheinlichkeit an, dass Frauen um mindestens X kürzer sind als die Mahlzeiten, ähnlich der Tabelle und dem Diagramm unten.

Dies ist möglicherweise der beste Weg, dies zu quantifizieren, aber hier ist ein Skript zum Erstellen der obigen Tabelle:
Names default to here(1);
dt = Open("$Sample_data/Big Class.jmp");
// Column to adjust the difference in means between levels
nc = dt << New Column("height differenced", Numeric, "Continuous", Format("Best", 12), Formula(Parameter({b0 = 5}, If(:sex == "F", :height + b0, :height))));
distances = index(-2,7,incr=.5);
pvalless = {};
pvalmore = {};
for(d=1, d<= n items(distances), d++,
dist = distances[d];
Eval( Eval Expr( nc << Set Formula( Parameter({b0 = expr( dist ) }, If(:sex == "F", :height + b0, :height))) ) );
ow = dt << Oneway(
Y( nc ),
X( :sex ),
Means( 1 ),
t Test( 1 ),
Mean Diamonds( 1 ),
SendToReport( Dispatch( {}, "t Test", OutlineBox, {Close( 1 )} ) )
);
//Extract the prob
pvalless[d] = ((ow << XPath("//OutlineBox[text()='Pooled t Test']"))[1][NumberColBox(4)] << get as matrix)[2];
pvalmore[d] = ((ow << XPath("//OutlineBox[text()='Pooled t Test']"))[1][NumberColBox(4)] << get as matrix)[3];
ow << close window;
);
dtSum = New Table( "Results",
Add Rows( n items(distances) ),
New Column( "Distance",
Numeric,
"Continuous",
Format( "Best", 12 ),
Set Values( distances )
),
New Column( "pvalueless",
Numeric,
"Continuous",
Format( "Best", 12 ),
Set Values( pvalless )
),
New Column( "pvaluemore",
Numeric,
"Continuous",
Format( "Best", 12 ),
Set Values( pvalmore )
)
);
