EDISON-package {EDISON} | R Documentation |

## Allows for network reconstruction and changepoint detection.

### Description

This package runs an MCMC simulation to reconstruct networks from time series data, using a non-homogeneous, time-varying dynamic Bayesian network. Networks segments and changepoints are inferred concurrently, and information sharing priors provide a reduction of the inference uncertainty.

```
# Generate random gene network and simulate data from it
dataset = simulateNetwork(l=25)
# Run MCMC simulation to infer networks and changepoint locations
result = EDISON.run(dataset$sim_data, num.iter=500)
# Calculate posterior probabilities of changepoints
cps = calculateCPProbabilities(result)
# Calculate marginal posterior probabilities of edges in the network
network = calculateEdgeProbabilities(result)
