The upper right quadrant shows in Roman font the covariance of the fitted parameters established by bootstrapping (see Materials and methods). The diagonal are the parameter variances. The lower left quadrant shows the correlation coefficients in Italic. Units for the parameters are the same as in Table 1. While we report these values, we emphasize that these values must be interpreted with care since posterior distributions of the parameters are sloppy [49] and do not look like multivariate normal distributions. Instead they show long nonlinear ridges of parameters with nearly-equivalent likelihoods.
