<div dir="ltr">My understanding is that a baseline of NaN means that there is no baseline, whereas an empty baseline value uses the average as a baseline. This baselining, however, is independent of the bootstrapping. If you are not inputting a baseline vector into bootstat, then I believe it just tests the ERSP against an average baseline. I've been calling bootstat directly, outside of the GUI/pop_newtimef or newtimef, so I don't know off hand if it is possible to add this baseline vector to bootstat as an input in the GUI / pop_newtimef / newtimef. I've been asking several questions about ERSP statistics myself, so if you search for my question on the mailing list, my thought process and the comments I've received may be helpful. That being said, I am also in the process of trying to understand things, so don't take what I'm saying as the end-all-be-all.<div><br></div><div>If I am interpreting things correctly, I think that it does not matter per se how you've baselined the ERSP prior to running the bootstrap statistic, so long as it makes sense for what you are trying to do- in other words, I think that's just an empirical or theoretical question. Likewise, whether the bootstrap statistic should be tested against an average baseline or a specific window of the ERSP seems like an empirical/theoretical question to me. </div><div><br></div><div>I guess the long and short of it is to make sure you are doing whatever makes the most empirical or theoretical sense for you, and that how you baseline the ERSP is separate from what baseline you use to statistically test against your ERSP.</div><div><br></div><div>Best,</div><div>Max</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Nov 6, 2017 at 2:03 PM, Tarik S Bel-Bahar <span dir="ltr"><<a href="mailto:tarikbelbahar@gmail.com" target="_blank">tarikbelbahar@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div class="gmail_default" style="color:#333399">Hello Nabi, </div><div class="gmail_default" style="color:#333399"><br></div><div class="gmail_default" style="color:#333399">1. I'm not 100% sure, but the significance levels are probably significant compared to the baseline you have set. If you have no baseline set, they are probably set to the whole time period. You probably want to play around setting the baseline to different settings, in order to get a better feel for how the ersp baselining and significance works.
