Version log E-book "Mechanistic modelling essentials" Version 0.2 (Date 28 August 2021) - First version of this book that is placed on Leanpub. Version 0.3 (Date 2 November 2022) - Small changes to the text in various places for clarification/readability. For example, removed reference to SSQ in Ch. 5, which is confusing as likelihood was introduced extensively in the previous chapter. Also added more explanation in places, such as adding an example with 'separation of variables' to solve a simple ODE. - Added a chapter on TK modelling principles, with focus on the various fate processes: advection, diffusion, active transport, transformation. This should provide more background for the simple one-compartment, first-order, TK model that is so commonly used. - Moved the sections from the chapter "Miscellaneous stuff" to the other chapters on statistics. I expanded them slightly to make them more readable, and fit in better. Version 0.4 (Date 14 June 2023) - Expanded the chapter on toxicokinetic principles. Added sections for effects of size/growth on TK, effects of reproduction on TK, and saturating kinetics. - Added a short chapter on toxicodynamic principles. This book is not the place to redo the work presented in my other e-books, but some more general principles are worth explaining. - Some small changes to the text for clarification and error repair. ================================== Updates planned - ...
