Spaghetti plot of resampled posterior fits

Spaghetti plot of resampled posterior fits

Usage

plot_simulations(obsdata, fit, sim_fn, method = "auto", n = 200, ...)

Arguments

obsdata

The observational data. The data in this will typically be a named list, but could be anything, e.g. dataframe. It is the reference data that the simulation model is aiming to replicate.

fit

A S3 abc_fit object as output by the abc_XXX functions

sim_fn

a user defined function that takes a set of parameters named the same as priors_list. It must return a simulated data set in the same format as obsdata, or that can be compared to simdata by scorer_fn. This function must not refer to global parameters, and will be automatically crated with carrier.

method

one of "auto", "count", or "density", or a named vector one for each component of obsdata.

n

the number of simulations to plot

...

Named arguments passed on to posterior_resample

n_resamples

the number of resamples for each parameter combination.

max_samples

the maximum total number of resamples to pick.

Value

a patchwork of ggplots
