Detailed Description

Logarithmic Nash Sutcliffe Efficiency.

Calculates the Logarithmic Nash Sutcliffe Efficiency

\[LNNSE = \frac{\sum_i(\ln(y_i) - \ln(x_i))^2} {\sum_i (\ln(x_i) - \ln(\bar x))^2 }\]

where \( x\) is the observation and \( y\) is the modelled data.
If an optinal mask is given, the calculations are over those locations that correspond to true values in the mask. Note that the mask is intent inout, since values which are less or equal zero will be masked additionally. \( x \) and \( y\) can be single or double precision. The result will have the same numerical precision.

Example

vec1 = (/ 1., 2, 3., -999., 5., 6. /)
vec2 = (/ 1., 2, 3., -999., 5., 6. /)
m   = lnnse(vec1, vec2, mask=(vec >= 0.))
--> m = 1.0

See also example in test directory.

Parameters

[in]	real(sp/dp), dimension() :: x, y	1D/2D/3D-array with input numbers.
[in]	logical, optional :: mask	1D/2D/Array-array of logical values with size(x/y). If present, only those locations in vec corresponding to the true values in mask are used.

Return values

real(sp/dp) :: LNNSE

LNNSE.

Note

Input values must be floating points.
