Climate-induced changes in lake ecosystem structure inferred from coupled neo- and paleo-ecological approaches. Ecology 93:2155–2164. http://dx.doi.org/10.1890/11-2218.1

Appendix C. Equations used for (a) weighted averaging inference model, and (b) error estimates as root mean square error of prediction (RMSEP).

(a)

Where: i = the inferred value for mixing depth
yk = the abundance of taxon k in the fossil sample
uk = the mixing depth optimum of taxon k

for species 1 ( = k) through m

(b)

Where: xi = the measured value for mixing depth in sample i
i = the inferred value for mixing depth in sample i

for samples 1 ( = i) through m
