Hi.

I am a user of Stata and I am not used to R, but I need to create a linear regression separated by years.

Can anyone help me? I put the data in here https://drive.google.com/drive/folders/1KoE0kay_mkAkn4fPHbMx3NcG6guHrp19?usp=sharing

The code in Stata is at follows:

reg interes year

reg interes edad if year==2010

est sto _mod1

reg interes edad if year==2012

est sto _mod2

reg interes edad if year==2014

est sto _mod3

reg interes edad if year==2016

est sto _mod4

reg interes edad if year==2006

est sto _modA

reg interes edad if year==2008

est sto _modB

coefplot (_mod1, label(2010)) (_mod2, label(2012))(_mod3, label(2014)) (_mod4, label(2016)), drop(?cons) xline(0) scheme(lean1) scale(0.8)

set scheme s1mono

coefplot (_modA, label(2006))(_modB, label(2008))(_mod1, label(2010)) (_mod2, label(2012))(_mod3, label(2014)) (_mod4, label(2016)), drop(?cons) xline(0) scale(0.8)

twoway lfitci interes edad

twoway lfitci interes edad, by(year)

I have tried this in R but it doesnt work:

fit<- lm(formula=interes~edad if year==2010 ,data=ESS)

summary(fit)
