Get_MCMC_parameters {BayesGrowth}

Get_MCMC_parameters

Description

Get parameter summary statistics from the outputs of a Estimate_MCMC_Growth object. It is simplified set of results than is returned from summary(obj).

Usage

Get_MCMC_parameters(obj)

Arguments

obj

An output from the Estimate_MCMC_Growth function

Value

A data.frame with the posterior distributions for each parameter. These include the mean, Standard error of the mean, Standard deviation of the mean, median, 95th percentiles, effective sample sizes and Rhat.

Examples

# load example data
data("example_data")
## Biological info - lengths in mm
max_size <- 440
max_size_se <- 5
birth_size <- 0
birth_size_se <- 0.001 # an se cannot be zero

# Use the function to estimate the rstan model
fit <- Estimate_MCMC_Growth(data = example_data,
                            Model = "VB" ,
                            iter = 5000,
                            Linf = max_size,
                            Linf.se = max_size_se,
                            L0 = birth_size,
                            sigma.max = 100,
                            L0.se = birth_size_se,
                            k.max = 1,
                            n_cores = 1)
