Nonlinear Regression with R Trainer Dr. András Aszódi VBCF BioComp, Vienna • He has extensive compu - tational biology experience - both in academia and industry • He is currently working at the Bioinformatics and Scientific Computing Core Facility at the Vienna Bio-center Campus. It comes with a lot of nonlinear models, which are useful to describe several biological processes, from plant growth to bioassays, from herbicide degradation to seed germination. R packages for both classical and robust nonlinear regression are presented in detail in the book and on an accompanying website Robust Nonlinear Regression: with Applications using R is an ideal text for statisticians, biostatisticians, and statistical consultants, as well as advanced level students of … To this end, we introduce a unied diagnostic framework with the R package nlstools.
