i'm tryin to do PCA, and i have ~5000 responders, ~1100 questions, and around 950 responders per question. i havent looked at how much each question has direct responder overlap with any other given question on average but im guessing i probably need more than 950

Hey, I gave a lot of responses yesterday, but after about 15-20 minutes I got an error message with every question/answer saying my answer could not be saved. Maybe it was only a one off error, but I thought I'd let you know.
