nlsList.selfStart: nlsList Fit from a selfStart Function
Description
The response variable and primary covariate in formula(data)
are used together with model to construct the nonlinear model
formula. This is used in the nls calls and, because a
selfStarting model function can calculate initial estimates for its
parameters from the data, no starting estimates need to be provided.
Usage
## S3 method for class 'selfStart':
nlsList(model, data, start, control, level, subset, na.action, pool)
Arguments
Value
a list of nls objects with as many components as the number of
groups defined by the grouping factor. A NULL value is assigned
to the components corresponding to clusters for which the nls
algorithm failed to converge. Generic functions such as coef,
fixed.effects, lme, pairs, plot,
predict, random.effects, summary, and
update have methods that can be applied to an nlsList
object.
