Thank you for the fast help! I am not sure though if I understand the predict.lm business. The newdata that I would make predictions from consists of six matrices, one for each variable. Do I cbind the matrices like...

Hi, thank you for taking the time and reading my question. My question is twofold: 1. I have several matrices with variables and one matrix with water levels. I want to predict the water level with the data in the...
