Dear Yung-jin,

❝ For all zero concentrations, AUC_0-inf is zero. So it crashes. Also to estimate the terminal phase elimination rate constants (k_el), it requires none-zero data from terminal phase to perform linear regression (to get a slope). It certainly stops the run at this step too.

Could you implement in Bear the approaches described by Helmut and ElMaestro in this thread?
As I understand, according to the EMA GL we can exclude the data of volunteers without evaluable data for both TIMP and RIMP.
In case we don't exclude them and try to estimate the PK parameters, Phoenix and SAS will ignore them and take into account as missing values.
So it would be great if Bear will get these options for "null" PK parameters (to exclude the volunteer from analysis or take these data as missing)

Kind regards,
Mittyri
