The 'data' argument and scoping in nls
...of relevant help pages,
but nothing on a strategic level, what general approach should I use? Can
someone point me in the right direction?
I'm using nls to fit models where some non-optimised parameters are
different lengths from the data, often matrices, something like this ...
----------
SSfunc <- selfStart(
model = function(x, Coeff, A)
{
},
initial = function(mCall, data, LHS)
{
},
parameters = c("Coeff")
)
y <- ...
x <-...
A <- ...
nls(y ~ SSfunc(x, Coeff, A), data=...)
--------------------
... where A may be a matrix. This me...
