Jamovi slows down (to a halt) when trying to perform PCA
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 (wavelen...

Re: Improving ROC curves - Youden index
Hey folks, the update has been pushed to jamovi. The DIF table error is gone, a crude DeLong test for differences between AUC's has been added, and the ability to combine ROC plots into a single image has been added. Please try it out and let me know your thoughts! Thanks! I just need to find it wh...

Re: Improving ROC curves - Youden index
Hello guys This is the code that I used: To clarify: Volumen = name of the dataset that I used Responder = name of the response variable (0 or 1) CVP, PPV, PCWP, SVV = predictor variables (continuous) rocCVP <- roc (Volumen$Responder, Volumen$CVP, percent = TRUE) rocPPV <- roc (Volumen$Responder, Vo...
