View Full Version : PCA: How many dimensions are enough?

07-17-2018, 10:36 PM
When plotting PCAs for human genetics, usually up to 10 or 25 principal components are included. So, the question is, how beneficial is plotting the higher dimensions (e.g., PC50, PC100, etc.) towards modelling accurate population structures?

How does one generate data up to PC100, or much higher?
