bear v2.7.1 [🇷 for BE/BA]
Dear all,
I have released bear v2.7.1 to sourceforge. The major change was to fix the reported error. The error will occur if there is any zero conc. included when calculating λz (the terminal-phase elimination rate constant). It's because log(0) is equal to
I have released bear v2.7.1 to sourceforge. The major change was to fix the reported error. The error will occur if there is any zero conc. included when calculating λz (the terminal-phase elimination rate constant). It's because log(0) is equal to
-Inf
as shown in error message. If switching to manual selection of data points to avoid this error (not to select any zero conc.), it may complete the run without any error. However, it will result with AUC0-t = AUC0-inf and AUCt-inf (extrapolated AUC) = 0 since Clast = 0. Actually, I don't know if we should call it as AUC0-t or AUC0-inf by definition. Although this has been mentioned in bear's website about data input, I decided to fix this error by throwing 'NA' to replace any conc. = 0 occurring at time ≠ 0. This error was also reported elsewhere (1 & 2) at this Forum by other users. Thanks for reading.❝ ❝ Error in
