%description
Models the relationship between dose levels and responses in a
pharmacological experiment using the 4 Parameter Logistic model.
Traditional packages on dose-response modelling such as 'drc' and 'nplr'
often draw errors due to convergence failure especially when data have
outliers or non-logistic shapes. This package provides robust estimation
methods that are less affected by outliers and other initialization
methods that work well for data lacking logistic shapes. We provide the
bounds on the parameters of the 4PL model that prevent parameter estimates
from diverging or converging to zero and base their justification in a
statistical principle. These methods are used as remedies to convergence
failure problems.  Gadagkar, S. R. and Call, G. B. (2015)
