Problem with 'nls' fitting logistic model (5PL)
Dear R-Helpers,
I'm working with immunoassay data and 5PL logistic model. I wanted to
experiment with different forms of weighting and parameter selection,
which is not possible in instrument software, so I turned to R.
I am using R 2.14.2 under Win7 64bit, and the 'nls' library to fit the
model - I started with the same model and weighting ty...

Including a text file (JAGS model) in an R package
...39;ve tried demo, inst, data and man.
Is it possible to do this? If not, how can I go about including a JAGS model in an R package example?
Regards,
CONOR.

Fitting ELISA measurements "unknowns" to 4 parameter logistic model
Hello,
I am trying to fit my Elisa results (absorbance readings) to a standard
curve. To create the standard curve model, I performed a 4-parameter
logistic fit using the 'drc' package (ExpectedConc~Absorbance). This gave me
the following:

A 'drc' model.
Call:
drm(formula = Response ~ Expected, data = SC, fct = LL.4())
Coefficients:
b:(Intercept) c:(Intercept)
