Adding a correlation value (like Rsquared) to a 4 parameter logistic fit model.
...nd a way to add a correlation value (such as an R squared or
something similar) so we can test different solvents in making this standard
curve. We currently use the drc package and this is our script for the 4
parameter:
SC<-read.delim(file = "C:/Documents and Settings/rekem/My
Documents/SCBook.txt", header = T, check.names = FALSE, as.is = TRUE)
FourP<-drm(Response~Expected, data = SC, fct = LL.4())
plot(FourP, main = "LTB4 Standard Curve Zi Phase 7", xlab = "Expected
(pg/mL)", ylab = "Response (%Bound)")
Thanks for any help.
