Hi guys :wave:, I make balance simulation of load profile electric vehicle chargers in R. I use CHADEMO (45 kW). I need to genarate a lot of profiles. I can make one profile, but it is not convenient. See example: Chademo1=numeric(1440) ### minute time axis a day for...
3. ### Chauvenets criterion and multivariate analysis

Hi Is it a function that could be used in R to run Chauvenets criterion to reject outliers in a data set? Or does it have to be done manually by calculating the mean, standard deviation, probability etc? Also for multivariate analysis in R, what type of analyses can you use when one...
