how long should follow-up be for the outcome how is a longer follow-up period influencing the model how long should i wait for baseline why is follow-up period shorter how to predict event sensitivity why are the follow-up periods shorter in a classifier model when should outcome time be varying in longitudinal studies why are results shorter for supervised classifier model which variable is a binary variable? why would you need to follow up for the second year how long can you follow up an independent test what is an advantage of a shorter follow up period how does varying outcome duration affect model performance? how is the follow up period different between studies? which variable is a binary variable? what is the difference between baseline and follow up on outcome how should a longer follow up period be expected how long do you need to follow up on a model? how long does it take for a supervised discriminant model to validate? why are follow up periods shorter
