{title:Module to generate a score}

{p 8 14 2}{cmd:genscore} {it:varlist} [{cmd:if} {it:exp}] [{cmd:in} {it:range}] [{it:weights}] [{cmd:,} {cmdab:sc:ore}({it:newvarname}) {cmdab:me:an} {cmdab:cent:ered} {cmdab:sta:ndardized} {cmdab:mi:ssing}(string) {cmdab:rep:lace}]

{title:Description}

{p 4 8 2}{cmd:genscore} allows creating a new variable containing the score
computed as the sum (or the mean) of the responses to the variables defined in 
{it:varlist}. Variables of {it:varlist} can be centered or standardized. The new
variable will contain a missing value for each individual with at least one
missing values  among the variables of {it:varlist}.

{p 4 8 2}Only {cmd:fweights} are allowed, and the weights have an influence only with
the {cmd:centered} or {cmd:standardized} options.

{title:Options}

{p 4 8 2}{cmd:score} defines the name of the new variable ({it:score} by default).

{p 4 8 2}{cmd:mean} allows obtaining a mean score (the sum of the responses is divided by the number of variables).

{p 4 8 2}{cmd:centered} computes the scores with centered variables.

{p 4 8 2}{cmd:standardized}  computes the scores with standardized variables.

{p 4 8 2}{cmd:missing} defines a specific modality of the variables which can be considered as a missing value.

{p 4 8 2}{cmd:replace} allows replacing the variable defined in the {cmd:score} option if it already exists.

{title:Examples}

{p 4 8 2}{cmd:. genscore turn trunk mpg [fweight=w],standardized mean}

{p 4 8 2}{cmd:. genscore item1-item20, score(totscore) missing(9)}

{p 4 8 2}{cmd:. genscore var*, score(scorevar) replace}
