{bf: spweightcs: Cross Section Spatial Weight Matrix}

{bf:{err:{dlgtab:Syntax}}}
{phang}

{cmd: spweightcs} {varlist} {cmd:,} {opt p:anel(numlist)} {opt m:atrix(weight_name)} {opt not:abel}

{bf:{err:{dlgtab:Description}}}

{p 2 2 2} spweightcs creates or generates cross section spatial weight matrix among neighbor locations, for using in spatial regression analysis.{p_end}

{p 2 2 2} Raw data for neighbor locations must be put as shown in the sample data file {cmd: (spweightcs.dta)}.{p_end}

{p2colreset}{...}
{bf:{err:{dlgtab:Options}}}

{col 4}{opt p:anel}{col 15}Number of all locations units

{col 4}{opt m:atrix}{col 15}Specify name of spatial weight matrix, that will be created

{col 4}{opt tab:le}{col 15}Display Cross Section Spatial Weight Matrix Table

{bf:{err:{dlgtab:Saved Results}}}

{p 2 4 2 }{cmd:spweightcs} saves the following results in {cmd:e()}:

Matrixes
{col 4}{cmd:e(wcs)}{col 15}Cross Section Spatial Weight Matrix.{p_end}

{bf:{err:{dlgtab:Example}}}

	{stata clear all}

	{stata sysuse spweightcs.dta, clear}

	{stata spweightcs v1 v2 , panel(7) matrix(W)}

	{stata spweightcs v1 v2 , panel(7) matrix(W) table}

	{stata ereturn list}

	{stata db spweightcs}

{p 2 2 2} The final shape of cross section spatial weight matrix will be as follows:.{p_end}

{p 2 2 2} After creating spatial weight matrix, you can use {helpb spautoreg} (if installed) to generate eigenvalues vector and standardized weight matrix.{p_end}
