Hello R-users, Does anyone know how to set initial values in lme? I have a problem of non convergence and would like to try different inital values. Is lmeScale the right function to do it and how many parameters do we need to specify, only fixed parameters or also random effects ? Thanks for any advice, Best regards, -- THAI Hoai Thu INSERM U738 - Universit? Paris 7 16 rue Henri Huchard 75018 Paris, FRANCE Tel: 01 57 27 75 39 Email: hoai-thu.thai at inserm.fr
