Group Project Dynamics— how to present advanced ideas without offending others?
You don't have to do anything with this situation any more - your colleague is clearly feeling uncomfortable about it and as you said in comments, reaching out to her now might very easily come across as patronising.

For the next time, I'd advise going through the analysis with her before presenting to the group. Ideally, you'd do this a couple of times as your analysis progresses, and take her initial results as a starting point.

In analyses and presentations, you should never shy away from using complex methods if you feel they are necessary. However, you should also be able to explain them in such a way that your whole audience can understand what you are doing and why.
