Jamovi slows down (to a halt) when trying to perform PCA
Posted: Mon Dec 20, 2021 11:29 am
Can you help me with this please...
I have a set of 20 patients (rows). Each of them was measured tooth enamel light absorbance and i have a table with absorbances for each wavelength (columns).
We are talking around 4000 data cells for each patient.
When I enter PCA and add those variables (wavelengths) - i select all of them (shift select) and click the right arrow (like many times before).... And it halts (it doesn't say not responding like a crashed app would do).
I know it is a large dataset... But is this normal?
It's been sitting there for 20 minutes... Should I wait more?
