Dear tshianza, The error may occur when trying to include a value of '0' or any non numeric (character, such as 'BLQ', "BLOQ' or 'BLLOQ') to do linear regression for the terminal elimination rate constant (i.e., λz). So please look at your dataset and remove the rows with conc. = 0 or = 'non numeric' (except data point with the time = 0). Then it should work. ❝ And I'm unsure of how my data should be adjusted — All the best, -- Yung-jin Lee bear v2.9.1:- created by Hsin-ya Lee & Yung-jin Lee Kaohsiung, Taiwan https://www.pkpd168.com/bear Download link (updated) -> here |
