summary.fixest.fixef

Summary method for fixed-effects coefficients

Description

This function summarizes the main characteristics of the fixed-effects coefficients. It shows the number of fixed-effects that have been set as references and the first elements of the fixed-effects.

Usage

## S3 method for class 'fixest.fixef'
summary(object, n = 5, ...)

Arguments

`object`	An object returned by the function `fixef.fixest`.
`n`	Positive integer, defaults to 5. The `n` first fixed-effects for each fixed-effect dimension are reported.
`...`	Not currently used.

Value

It prints the number of fixed-effect coefficients per fixed-effect dimension, as well as the number of fixed-effects used as references for each dimension, and the mean and variance of the fixed-effect coefficients. Finally, it reports the first 5 (arg. n) elements of each fixed-effect.

Examples

data(trade)

# We estimate the effect of distance on trade
# => we account for 3 fixed-effects effects
est_pois = femlm(Euros ~ log(dist_km)|Origin+Destination+Product, trade)

# obtaining the fixed-effects coefficients
fe_trade = fixef(est_pois)

# printing some summary information on the fixed-effects coefficients:
summary(fe_trade)
