Simulating and estimating, what about model (mis)match?

Introduction

{% include markup/info %} This tutorial contains hands-on material that we use for the MEG connectivity workshop in Chieti. {% include markup/end %}

Background

{% include /shared/tutorial/connectivity_simulation_background.md %}

Procedure

We will simulate (virtual) channel-data and use it to compute various connectivity metrics. As a generative model of the data we will use a multivariate autoregressive model and we will use ft_connectivitysimulation for this. Subsequently, we will estimate the multivariate autoregressive model and the spectral transfer function, and the cross-spectral density matrix using the functions ft_mvaranalysis and ft_freqanalysis. In the next step we will compute and inspect various measures of connectivity with ft_connectivityanalysis and ft_connectivityplot.
