The unbiased estimation of the fraction of variance explained by a model

Comparison of 
with published estimators of 
on the basis of simulated and real data.
(A) Low SNR (0.25) simulation where estimators on vertical axis are sorted from top to bottom by smallest MSE with respect to estimating 
. Traces show mean and SD of each estimator. (B) Same simulation at higher SNR (1.0) but same m, n. (C) Estimated fit of DNN to V4 data by 
and published estimators. Each trace is the estimated fit of the model for one neural recording.
