### See Also

See also the main estimation functions `femlm`, `feols` or `feglm`. Use `summary.fixest` to see the results with the appropriate standard-errors, `fixef.fixest` to extract the fixed-effects coefficients, and the function `etable` to visualize the results of multiple estimations.

### Examples

    # simple estimation on iris data with "Species" fixed-effects
    res = femlm(Sepal.Length ~ Sepal.Width + Petal.Length +
                Petal.Width | Species, iris)

    nobs(res)
    logLik(res)
