{title:Description}

{pstd}
{cmd:skprobit} Performs a Lagrange Multiplier Test for the Normality of the residuals of
a Probit model of depvar on indepvars.

{hi:skprobit} is not an official Stata command. The usual disclimers apply: all errors
and imperfections in this package are mine and all comments are very welcome.



{title:Return values}

{col 4}Scalars
{col 8}{cmd:r(N)}{col 27}Number of observations used
{col 8}{cmd:r(chi2_p)}{col 27}p value of the chi-squared statistic
{col 8}{cmd:r(chi2)}{col 27}Chi-squared statistic

{p 4 8 2}{stata "sysuse auto"}{p_end}

{p 4 8 2}{stata "probit foreign weight mpg"}{p_end}

{p 4 8 2}{stata "skprobit foreign weight mpg"}{p_end}

{p 4 8 2} The result shows that the Ho (Normality) hypothesis of the residuals is rejected
in this example. The residuals are not normal in this case.

{p 4 8 2}{stata "skprobit low age lwt race smoke ptl ht ui"}{p_end}

{p 4 8 2} The result shows that the Ho (Normality) hypothesis of the residuals is not rejected
in this example. Hence the residuals are normal in this case.

{p 4 8 2}{stata "skprobit union age grade not_smsa"}{p_end}

{p 4 8 2} The result shows that the Ho (Normality) hypothesis of the residuals is rejected
in this example. The residuals are not normal in this case.
