coef.drc(object, ...)

Arguments

object an object of class 'drc'.
... additional arguments.

model1 <- multdrc(FA)
coef(model1)

model2 <- multdrc(FA, boxcox=TRUE)
summary(model2)  # not a satisfactory fit

## Usinf estimates from 'model1' as start values
model3 <- multdrc(FA, boxcox=TRUE, startVal=coef(model1))
summary(model3)  # a satisfactory fit

rm(model1, model2, model3)
