No R^2 Value for Linear Fit

robot — Fri, 06 Oct 2017 18:38:54 GMT

Hi,

I have a data set with 2 rows of data. If I run Fit Special and constrain intercept = 0, no R^2 value is reported. If I have 2 data points and only 1 degree of freedom (slope), should I get an R^2 value, or am I missing something?

I am using JMP12.2. Thanks!

dt = New Table( "Data",
	Add Rows( 2 ),
	New Column( "x", Numeric, "Continuous", Format( "Best", 12 ), Set Values( [1, 2] ) ),
	New Column( "y", Numeric, "Continuous", Format( "Best", 12 ), Set Values( [1.1, 2.1] ) )
);
dt << Bivariate( Y( :y ), X( :x ), Fit Special( Intercept( 0 ) ) );

Nevermind. I found my answer here: http://freakonometrics.hypotheses.org/2343.
