Information about "GUTS, a comprehensive guide"
This page contains information
about the e-book on GUTS
entitled: "Modelling survival under chemical stress. A
comprehensive guide to the GUTS framework." The first
version was released on 18 January 2018. This book is
co-written by Tjalling
Jager and Roman
Ashauer, as part of a Cefic-LRI
funded project. The book contains a detailed
description of GUTS (both conceptual and mathematical), its
special cases, and the associated statistics. Case studies
will be included to illustrate how to use GUTS on actual
data sets, and much, much more.
The book is offered through the Leanpub publishing
framework. As with the other e-books,
you have the opportunity to download it for free, but you
also have the option to pay for it. Please consider this
option, for it will allow us to dedicate time and effort to
updating this e-book, and writing new ones. In any case, it
is good to download this e-book from Leanpub yoursefl, as
you will be informed automatically when we release a new

Leanpub (Version 2.0 of 8 December 2018) or check out
the first 15 pages here.
- Check the version/error
log for changes relative to the previous version,
known errors in the current version, and parts that we
will modify/clarify in the next update.
- Check out the list of survival papers over here. At this
moment, the list only contains papers using the hazard
formulation (i.e., GUTS-SD, GUTS-RED-SD, and its

Where can I find software to do 'GUTS' analyses?
Matlab-based software packages are
offered on the BYOM pages. All GUTS
cases can be run. Links to other freely-downloadable
software (such as two R-packages for GUTS, and several
standalone versions) is collected over
here. In the book, we also present the results from a
ring test with 11 software implementations. Not all of them
are available yet for free-downloadable yet (they will be
included in the software section of this website when they
do). Note that we are currently developing a user-friendly
standalone software in a Cefic-LRI
Ring test information
Data sets used for the GUTS ring
test (as presented in Chapter 7 of the e-book) can be downloaded
here as Excel file.
A detailed listing of the parameter estimates and
predictions (with confidence intervals) for the BYOM analyses has been collected into
a report. Download
here. This is an updated version, using BYOM v. 4.2b
and GUTS v. 2.2 (both with a few updates to increase speed
and accuracy, and correcting a small error). There are some
differences with the earlier BYOM analysis (as went into the
e-book), which are discussed in the PDF. Filesize is pretty
large due to the parameter-space plots that I included. This
is the version of 19 August 2018 (note that the version of
15 Aug. 2018 contained a silly error in calculations
involving time-varying concentrations).
