ZeligChoice is a module with additional models for the Zelig statistical package in R.
Project page and publications available at: http://zeligproject.org
ZeligChoice follows the same workflow as core Zelig.
Here us a simple example using the Zelig 4 wrappers (you can also use Zelig 5 reference classes). Note: installing and loading the zeligverse package will install and load all of the packages you need to use ZeligChoice.
# Load required packages
library(zeligverse)
# Load example data
data(mexico)
# Extimate model
z.out <- zelig(as.factor(vote88) ~ pristr + othcok + othsocok,
model = "mlogit", data = mexico, cite = FALSE)
# Set fitted values
x.out <- setx(z.out)
# Simulate quantities of interest
s.out <- sim(z.out, x.out)
# Plot results
plot(s.out)
You can install ZeligChoice from CRAN or, the developerment version from GitHub with:
# install.packages("devtools")
devtools::install_github("IQSS/ZeligChoice")
