adjusted_r_squared Function

public function adjusted_r_squared(p, x, xm, err) result(rst)

Computes the adjusted R-squared value for a data set.

The adjusted R-squared provides a mechanism for tempering the effects of extra explanatory variables on the traditional R-squared calculation. It is computed by noting the sample size $n$ and the number of variables $p$. $$\bar{R}^2 = 1 - \left( 1 - R^2 \right) \frac{n - 1}{n - p}$$ .

Arguments

Type	Intent	Optional	Attributes		Name
integer(kind=int32),	intent(in)			::	p	The number of variables.
real(kind=real64),	intent(in)			::	x(:)	An N-element array containing the dependent variables from the data set.
real(kind=real64),	intent(in)			::	xm(:)	An N-element array containing the corresponding modeled values.
class(errors),	intent(inout),	optional,	target	::	err	A mechanism for communicating errors and warnings to the caller. Possible warning and error codes are as follows. - FS_NO_ERROR: No errors encountered. - FS_ARRAY_SIZE_ERROR: Occurs if x and xm are not the same size.

Return Value real(kind=real64)

The result.
