{title:Description}
{p 8 8} 
The module {cmd:efgtg} estimates the FGT elasticities with respect to the total inequality, as weel as, to the within/between group components of inequality.

{title:Syntax}

{p 8 10}{cmd:efgtg}  {it:varlist}  {cmd:,} [ 
{cmd:HSize(}{it:varname}{cmd:)} {cmd:HGroup(}{it:varname}{cmd:)} {cmd:PLine(}{it:real}{cmd:)}  
{cmd:ALpha(}{it:real}{cmd:)} 
{cmd:PRC(}{it:real}{cmd:)} {cmd:INDex(}{it:string}{cmd:)} ]
 

{p}where {p_end}
{p 8 8} {cmd:varlist} Standard linving (income or total expenditures). {p_end}


{title:Version} 9.2 and higher.

{title:Remark}
 {p} Users should set their surveys' sampling design before using this module 
 (and to save their data files). If the sampling design is not set, simple-random sampling (SRS) will be automatically assigned 
by default.
{p_end}


{title:Options}

{p 0 4} {cmdab:hsize}        Household size. For example, to compute poverty at the invididual level, one will want to weight household-level observations by household size (in addition to sampling weights, best set in survey design). {p_end}

{p 0 4} {cmdab:hgroup}       The variable which captures the socio-demographic group to be used in the decomposition. For example, for an urban-rural decomposition of poverty, this variable could equal 1 for rural households and 2 for urban ones. The associated varlist should contain only one variable. {p_end}

{p 0 4} {cmdab:alpha}         To set the FGT parameter (alpha). By default, alpha=0.   {p_end}

{p 0 4} {cmdab:pline}        To set the poverty line. {p_end}

{p 0 4} {cmdab:prc}          percentage of change in total inequality (ex. prc = 1%). {p_end}

{p 0 4} {cmdab:dec}          To set the number of decimals used in the display of results. {p_end}
