{title:Description}
{p}{cmd:clorenz} can produces the following distributional curves for a given list of variables:{p_end}
{p 4 8}{inp:. Lorenz curves}{p_end}
{p 4 8}{inp:. Generalised Lorenz curves}{p_end}
{p 4 8}{inp:. Concentration curves}{p_end}
{p 4 8}{inp:. Generalised concentartion curves}{p_end}
{p 4 8}{inp:. Deficit share curves}{p_end}
{p}Linear interpolation is used to estimate these distributional curves for a given percentile. {p_end}
{title:Options}
{p 0 4} {cmdab:hweight} variable that indicates the sampling weight at household level. {p_end}
{p 0 4} {cmdab:hsize} variable that indicates the household size. For example, if the variable of interest is income per capita, one should weight observations by the household size.{p_end}
{p 0 4} {cmdab:hgroup} variable which indicates the household group. For example, this variable equals to 1 for households that live in rural area and 2 for those that live in urban area. When this option is used, varlist should contain only one variable. If values of the variable {it:hgroup} are labelled, the produced graphs contain automatically these labels. {p_end}
{p 0 4} {cmdab:rank} option to indicate the ranking variable. If this variable is selected, the concentration curves are estimated instead of the Lorenz curves. {p_end}
{p 0 4} {cmdab:generalised} If option yes is selected, the generalised Lorenz (concentration) curves are displayed instead of the Lorenz (concentration) curves. {p_end}
{p 0 4} {cmdab:ctitle} To indicate the title of the produced graph. {p_end}
{p 0 4} {cmdab:dif} If option yes is is selected, the difference between percentiles and the lorenz (concentration) curves are displayed. {p_end}
{p 0 4} {cmdab:lres} If option yes is selected, coordinates of curves are listed. {p_end}
{p 0 4} {cmdab:sres} To save coordinates of curves in a Stata file, indicate the name of this file with this option. {p_end}
{p 0 4} {cmdab:dgraph} If option no is selected, the graph is not displayed. By default, the graph is displayed. {p_end}
