### Functional form in Box estimation

Dear Moderator,

I would like to estimate the coefficent theta in a logistic functional form. My model is

y = exp(theta x) / (1+exp(\theta x) + e

How can I specify it in the box estimation?

Thank you,

Aktar

Dear moderator,

Is it possible to specify this logistic functional form to link my data?

Thank you,

Non-normality and collinearity are NOT problems!

Something like

Code: Select all

ls y=exp(c(1)*x)/(1+exp(c(1)*x))

Return to “Estimation”
