{pstd}
{it:diparm_options} is one or more {cmd:diparm(}{it:diparm_args}{cmd:)} options,
where {it:diparm_args} is either {cmd:__sep__} or anything accepted by the
{cmd:_diparm} command; see {helpb _diparm}.


{title:Description}

{pstd}
{cmd:_coef_table} is an enhanced version of {cmd:ereturn} {cmd:display}; see
{helpb ereturn}


{title:Options}

{phang}
{opt level(#)} supplies the significance level for the confidence intervals of
the coefficients; see {help level}.

{phang}
{opt first} requests that Stata display only the first equation and
make it appear as if only one equation was estimated.

{phang}
{opt neq(#)} requests that Stata display only the first
{it:#} equations and make it appear as if only {it:#} equations were
estimated.

{phang}
{opt plus} places a {hi:+} symbol at the position of the dividing line between
variable names and results on the bottom separation line produced by
{cmd:estimates display}.  This is useful if you plan on adding more output to
the table.

{phang}
{opt separator(#)} places a horizontal separator line between every {it:#}
auxiliary parameters.

{phang}
{opt notest} suppresses the test statistic and p-value for ancillary
parameters.

{phang}
{opt coeftitle(title)} specifies the title for the coefficient column of the
table.  This option is ignored if {cmd:eform()} is specified.

{phang}
{it:eform_option} is identified in {help eform_option}.  Also see
{hi:Exponentiated form} below.

{phang}
{it:diparm_options} is one or more {opt diparm(diparm_args)} options, where
{it:diparm_args} is either {opt __sep__} or anything accepted by the
{cmd:_diparm} command; see {helpb _diparm}.

{pmore}
Although {it:diparm_options} are allowed, we recommend that you identify
the number of ancillary parameters by setting {cmd:e(k_aux)}; see
{hi:Ancillary parameters}.

{title:Automatic behavior}

{pstd}
{cmd:_coef_table} displays the following scalars and macros in {cmd:e()}:

{p2colset 9 25 29 2}{...}
{p2col :scalar}description{p_end}
{p2line}
{p2col :{cmd:e(k_eq)}}number of equations in {cmd:e(b)}{p_end}
{p2col :{cmd:e(k_aux)}}number of ancillary parameters in {cmd:e(b)}{p_end}
{p2col :{cmd:e(k_extra)}}number
	of extra statistics stored in {cmd:e(b)}{p_end}
{p2col :{cmd:e(k_eform)}}number
	of equations allowed to be affected by an {it:eform_option}; by
	default, only the first equation is affected{p_end}
{p2line}

{p2col :macro}description{p_end}
{p2line}
{p2col :{cmd:e(diparm}{it:#}{cmd:)}}arguments
	to be supplied to {cmd:_diparm}{p_end}
{p2col :{cmd:e(diparm_opt}{it:#}{cmd:)}}extra
	options to be added to the call to {cmd:_diparm} for the ancillary
	parameter stored in equation {it:#}, typically {opt noprob}{p_end}
{p2line}
{p2colreset}{...}


{title:Ancillary parameters}

{pstd}
Although {it:diparm_options} are allowed, we recommend that you identify
the number of ancillary parameters by setting {cmd:e(k_aux)}; for example,

{pmore2}
{cmd:ereturn scalar k_aux = 2}

{pstd}
identifies that there are 2 ancillary parameters.  If you want to display a
transform of one or more ancillary parameters, identify them by setting
{cmd:e(diparm}{it:#}{cmd:)}; for example,

{pmore2}
{cmd:ereturn local diparm1 lnsigma, exp label("sigma")}

{pstd}
specifies the arguments to {cmd:_diparm}, just like {it:diparm_options}.


{title:Exponentiated form}

{pstd}
{cmd:_coef_table} will display the coefficient table in exponentiated form
when supplied with an {it:eform_option}; see {help eform_option}.

{pstd}
Although the {opt eform} and {opt eform(string)} options are always allowed,
the properties of the commands identified in {cmd:e(cmd)} and {cmd:e(cmd2)}
will determine which other {it:eform_option} is allowed (where the property
matches the option).  Thus in order for the {opt or} option to be allowed,
{cmd:e(cmd)} must have the "or" property; see {helpb program} for
information about setting the properties of programs.

{pstd}
{cmd:e(k_eform)} determines which equations are affected by an
{it:eform_option}; by default, only the first equation is affected.
