spanel-package: Spatial Panel Data Models

In spanel: Spatial Panel Data Models

Description

Fit the spatial panel data models: the fixed effect model, between model and the random effect model.

Details

Package:	spanel

Examples

 # Load data
 data(Produc)
 data("usaww")
 # fit the fixed function
 fx<-span(log(gsp) ~ log(pcap) + log(pc) + log(emp) + unemp,Produc,usaww,n=48,t=17,model="fe")
 # fit the random function
 summary(fx)
 #fit the between function
 be<-span(log(gsp) ~ log(pcap) + log(pc) + log(emp) + unemp,Produc,usaww,n=48,t=17,model="be")
 summary(be)
 # fit the random function
 ran<-span(log(gsp) ~ log(pcap) + log(pc) + log(emp) + unemp,Produc,usaww,n=48,t=17,model="re")
 summary(ran)
