Displaying 1 result from an estimated 1 matches for "vector_of_errors_of_parameter".

difference between nls and nlme approaches
...g satisfactory results. I have tried several
simplifications of the model with no particular success.
Right now I am using the first approach weighting the parameter with the
inverse of their error estimated with nls. I am using
the weights option with lme using something like:
weight=varFixed(~ 1/vector_of_errors_of_parameter) approach.
Am I out of my mind completely? or am I on a more or less right
direction?
Thank you very much to whoever tries to answer this question.
