Version log E-book "Technical background document" Version Beta 1 (Date 20 September 2012) - First test version of this book. Version Beta 1.1 (Date 11 February 2015) - Corrected error in the starvation boundary in Eq. 1.11 (L infinite should be Lm). - Corrected an error in the TK for the situation where reserve has a different composition than structure (the volume of the reserve in the calculation of the elimination rate should be corrected for the different affinity of the chemical for structure and reserve). - Changed my affiliations. - Changed to A4 paper size. Version Beta 1.2 (Date 14 August 2015) - Added a section on joint confidence regions (5.3.2). - Changed e-mail address and links to match the new format at debtox.info (old ones will continue to work). =============================================================== Errors and problems spotted with the current version that will be updated in the next release. - The "Making sense ..." e-book has been updated to provide a central position for the concept of 'damage' in DEBtox. However, the technical document does NOT YET reflect that. Effects are directly related to internal concentrations. I intend to update this, but this takes some time as a number of symbols will have to be modified. The DEBkiss e-book is already up-to-date, so I suggest to start there for a state-of-the-art model description. - Added a warning for the joint confidence region (Section 5.3.2) that propagating a frequentist sample from a joint parameter region cannot be done in the same way as for a Bayesian sample.
