Explained variance. a. Analysis of covariance. The plot shows percentage of variance explained by the three factors [variable] (var), [juice pair] (pair) and [variable × juice pair] (int), separately for the three response types. The percentage of explained variance is averaged across responses, pooling time windows. b. Linear fit. Since OFC responses are typically menu invariant, we can estimate the variance explained by the encoded variable with a simple linear regression. The histogram shows for different R2 (x-axis) the number of corresponding responses (y-axis), separately for the three response types. The medians of the three distributions are, respectively, 0.42, 0.44 and 0.46.
