formula format for parameter estimation
Hello, I am trying to input the following formula into R for parameter
estimation. I don't quite have the just of formula syntax. I understand
simple basic regression (y ~ x), but how do I do the ff:
y = ( b0*x )/(x + b1),
where b0 and b1 are parameters that need to be solved. Any
help/suggestions for a newbie would be much appreciated. thanks ./w

Re : stat question - not R question so ignore if not interested
For the first question x'(y-bx)<>0 or Cov(Ui,Xi)<>0 you have heterogeinity problem !
OLS estimator in this case in biased.
The bias is equal to (Exx')^{-1}Exu
You obtain obtain correct estimator by use instrumental variable or 2SLS ...

Re : A smal fitting problem...
May be you are also not familiar with statistic. the solution of
min \sum_{i=1}^{n} (y_{i}-b)^{2} is the mean. So the solution is
b<-mean(y)

Appropriate test for overdispersion in binomial data
Dear R users,
Overdispersion is often a problem in binomial data. I attempt to model a
binary response (sex-ratio) with three categorical explanatory variables,
using GLM, which could assume the form:
y<-cbind(sexf, sample-sexf)
model<-glm(y ~ age+month+year, binomial)
summary(model)
Output:
(Dispersion parameter for binomial family taken to be 1)
Null deviance: 8956.7 on 582
