Figure 2.

Joint parameter estimates for the synaptic-dynamics model. (A) Pairwise and individual posterior marginals for release-site number n, depression timescale τ_D, initial release probability p₀, and mean quantal amplitude μ_a. True parameter values and data are the same as Figure 1. Colorbars for the values of the posterior distributions are not shown; the relative differences in value show the shape and sharpness of the pairwise posteriors for each pair of parameters. (B) Pairwise posterior marginal for release site number n and initial release probability p₀ for a case where the true values were n = 35 and p₀ = 0.50 showing a strong anticorrelation. All posteriors shown after 10⁶ Metropolis-Hastings samples.
