The zelig function estimates a variety of statistical
zelig output with
sim to compute
quantities of interest, such as predicted probabilities, expected values, and
first differences, along with the associated measures of uncertainty
(standard errors and confidence intervals).
zelig(formula, model, data, ..., by = NULL, cite = TRUE)
a symbolic representation of the model to be
estimated, in the form
the name of a statistical model to estimate. For a list of other supported models and their documentation see: http://docs.zeligproject.org/articles/.

If is set to 'TRUE' (default), the model citation will be printed to the console.
Depending on the class of model selected,
zelig will return
an object with elements including
formula which may be summarized using
summary(z.out) or individually extracted using, for example,

functions to extract model components. You can also extract whole fitted
model objects using

Additional parameters avaialable to many models include:
weights: vector of weight values or a name of a variable in the dataset by which to weight the model. For more information see: http://docs.zeligproject.org/articles/weights.html.
bootstrap: logical or numeric. If
FALSE don't use bootstraps to
robustly estimate uncertainty around model parameters due to sampling error.
If an integer is supplied, the number of boostraps to run.
