Dear Matthew,
<div class=""><br class="">
</div>
<div class="">I think it depends on the way that you compute these metrics. If you approach it parametrically (i.e. using MVAR-models) I think that the coefficients are computed across all observations by default. If you want a leave-one-out estimate of the
coefficients, I think that you can use cfg.jackknife as an option to ft_mvaranalysis. How well this is supported throughout the rest of the analysis pipeline (i.e. ft_freqanalysis_mvar and ft_connectivityanalysis) I am not sure. I haven’t used this option
for a long time, so the code may have become a bit rusty here and there.</div>
<div class="">If you are using a non-parametric approach (i.e. using ft_freqanalysis, followed by ft_connectivity_csd2transfer, which is called on the fly by ft_connectivityanalysis), I think there used to be some functionality to compute leave-one-outs on
the fly, and then essentially treat them as ‘single trials’. Also there, I assume that the code has become a bit rusty, because it hasn’t been used for quite a while. Either way, I guess that an definitive answer to your question would require you to inspect
the code in some more detail.</div>

<div style="margin-top: 0px; margin-bottom: 0px;" class="">Greetings. Is it possible to use jackknife to get variance estimates for Granger, partial directed coherence and directed transfer function? I use it for wPLI, but cannot figure out how to do it for
these other measures.</div>
