Title

listcoef -- Listing regression coefficients with help for interpretation

General syntax

listcoef [varlist], [ pvalue(#)
[ factor | percent | std ]
constant reverse
gt lt adjacent
positive negative
expand
nolabel help
]

where varlist contains variables from the regression model for which
coefficients are to be listed.

Overview

listcoef lists the estimated coefficients for a variety of regression models.
Options allow you to specify different transformations of the coefficients,
such as factor change and percent change. Coefficients can be standardized for
a unit variance in the independent and/or dependent variables.
For mlogit, mprobit and slogit
coefficients for all comparisions can be listed.

Output for models with categorical outcomes is much clearer if you
assign value labels to the dependent variable.

Options

pvalue(#)
only coefficients with a significance level of # or smaller are printed.

factor
factor change coefficients are listed.

percent
percent change coefficients are listed.

std
coefficients standardized to a unit variance for the
independent and/or dependent variables are be listed.

constantoff
do not show constants in the output.

reverse
reverses the comparison implied by factor or percent change coefficients;
presents results indicating the change in the odds of b vs. a
instead of a vs. b.

vsquish
removes blanks rows sperating factor variables.

nofvlabel
display factor variable level values instead of labels.

help
includes details on the meaning of each coefficient.

Options for mlogit, mprobit, and slogit

gt
only comparisons where the first category has a larger
value than the second are printed (e.g., comparing outcome 2
versus 1, but not 1 versus 2).

lt
only comparisons where the first category has a smaller
value than the second are printed (e.g., comparing outcome 1 versus
2, but not 2 versus 1).

adjacent
only comparisons where the two category values are
adjacent are printed (e.g., comparing outcome 1 versus 2 or 2 versus
1, but not 1 versus 3).

positive
only comparisons where the coefficient is positive
are printed.

negative
only comparisons where the coefficient is negative
are printed.

nolabel
category numbers rather than value labels are used in the output.

expand
requests expanded output comparing all pairs of outcome categories
for slogit.

Compatable Models

listcoef can be used with clogit, cloglog, cnreg,
intreg, logistic, logit,
mlogit, mprobit, nbreg, ologit, oprobit,
poisson, probit, regress, rologit,
slogit, tobit,
zinb, zip, ztnb, and ztp.

Returns

listcoef creates returns r(table) that contains the
coefficients from the displayed table. For zip and zinb, r(table2)
contains coefficients from the inflation equation.
r(cmd) returns the name of the estimation command and r(pvalue)
the value specified with the pvalue() option.
