ivreg with fixed effect in R?
I want to estimate the following fixed effect model:
y_i,t = alpha_i + beta_1 x1_t + beta_2 x2_i,tx2_i,t = gamma_i + gamma_1
x1_t + gamma_2 Z1_i + gamma_3 Z2_i
I can use ivreg from AER to do the iv regression.
fm <- ivreg(y_i,t ~ x1_t + x2_i,t | x1_t + Z1_i + Z2_i,
data = DataSet)
But, I'm not sure how can I add the fixed effects.
Thanks!

MA process in panels
Dear R users,
I have an unbalanced panel with an average of I=100 individuals and a total
of T=1370 time intervals, i.e. T>>I. So far, I have been using the plm
package.
I wish to estimate a FE model like:
res<-plm(x~c+v, data=pdata_frame, effect="twoways", model="within",
na.action=na.omit)
?where c varies over i and t, and v represents an exogenous impact on x

which coefficients for a gam(mgcv) model equation?
Dear users,
I am trying to show the equation (including coefficients from the model
estimates) for a gam model but do not understand how to.
Slide 7 from one of the authors presentations (gam-theory.pdf URL:
http://people.bath.ac.uk/sw283/mgcv/) shows a general equation
log{E(yi )} = ?+ ?xi + f (zi ) .
What I would like to do is put my model coefficients and present the
equation used. I am an
