print.fixest: A print facility for 'fixest' objects.

In fixest: Fast Fixed-Effects Estimations

A print facility for fixest objects.

Description

This function is very similar to usual summary functions as it provides the table of coefficients along with other information on the fit of the estimation. The type of output can be customized by the user (using function setFixest_print).

Usage

## S3 method for class 'fixest'
print(x, n, type = "table", fitstat = NULL, ...)

setFixest_print(type = "table", fitstat = NULL)

getFixest_print()

Arguments

x	A fixest object. Obtained using the methods femlm, feols or feglm.
n	Integer, number of coefficients to display. By default, only the first 8 coefficients are displayed if x does not come from summary.fixest.
type	Either "table" (default) to display the coefficients table or "coef" to display only the coefficients.
fitstat	A formula or a character vector representing which fit statistic to display. The types must be valid types of the function fitstat. The default fit statistics depend on the type of estimation (OLS, GLM, IV, with/without fixed-effect). Providing the argument fitstat overrides the default fit statistics, you can however use the point "." to summon them back. Ex 1: fitstat = ~ . + ll adds the log-likelihood to the default values. Ex 2: fitstat = ~ ll + pr2 only displays the log-likelihood and the pseudo-R2.
...	Other arguments to be passed to vcov.fixest.

Details

It is possible to set the default values for the arguments type and fitstat by using the function setFixest_print.

Examples

# Load trade data
data(trade)

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

# displaying the results
#  (by default SEs are clustered if FEs are used)
print(est_pois)

# By default the coefficient table is displayed.
#  If the user wished to display only the coefficents, use option type:
print(est_pois, type = "coef")

# To permanently display coef. only, use setFixest_print:
setFixest_print(type = "coef")
est_pois
# back to default:
setFixest_print(type = "table")

#
# fitstat
#

# We modify which fit statistic to display
print(est_pois, fitstat = ~ . + lr)

# We add the LR test to the default (represented by the ".")

# to show only the LR stat:
print(est_pois, fitstat = ~ . + lr.stat)

# To modify the defaults:
setFixest_print(fitstat = ~ . + lr.stat + rmse)
est_pois

# Back to default (NULL == default)
setFixest_print(fitstat = NULL)
