Description
"NT1 ranges from infinite negative values to zero where zero indicates no
extrapolation beyond the univariate coverage of reference data"
(Mesgaran et al. 2014).
Usage
1
calc_NT1(refdat, prodat)
Arguments
refdat
A numerical matrix. The reference values of variables organized
in columns.
prodat
A numerical matrix. The projected values. The columns must
match those of refdat.
Notes
The code is adapted from Bell & Schlaepfer 2015 (available
at https://github.com/bellland/SDM.Virtual.Species_Bell.Schlaepfer)
which was based on a comment by Matthew Bayly made at
