Hi!
I am trying to perform a nonlinear regression using nls in a data.frame
where I have a lot of missing values (na's) in the response. I would like to
assign zero weight to those values. I have been looking to the nls help page and
there is some mention to na.action, with na.omit and na.fail as options, which
does not seem to suit me.
I need the missing values once my model is doing a numerical integration
over values of the independent values where I don't have the information of
the response.
my best regards,
IOsu
