- Fix SFORB coefficient matrix by treating SFORB models with metabolites with ilr as well - Calculate confidence intervals for parameters assuming normal distribution - Calculate confidence intervals for DT50 and DT90 values when only one parameter is involved - Fix DT50 and DT90 calculation for SFORB_SFO - Add unit tests for mkinfit - Document validation against fits documented in chapter 13 of FOCUS (2006) - Reproduce example anaylses (L1, L2, ...) in FOCUS (2006) - Generate confidence intervals for DT50 and DT90 values for other cases
