Creating an Index in Stata. 09 Dec 2017, 09:00. Dear Statalisters, I have searched the Internet now for over 2 hours, but it seems like no one had ever online  Hi all,. I am trying to create an index variable based on 7 variables all measuring the same concept. All 7 variables are 3-level ordinal variables, ranging from  Factor based scores only make sense in situations where the loadings are all similar. In that case, the weights wouldn't have done much anyway. Which Scores to  We introduce a user-written Stata command conindex which provides point The indices are estimated by making use of the correspondence of each to a  Please see the indexing documentation for much more on how to use an Index effectively.

in your example, if I want to use the family socio economic status as dependent variable in a regression, first I need to create the index and calculate the actual socio economic values. there might be also a direction problem such as some variables might increase the index while they are decreasing but others might increase the index while You want to add them up into one composite variable because they measure the same thing, if they meausure the same thing than they must be strongly correlated, if they don't, then they don't meausure the same thing and you don't want to add them to your composite index.

### PCA is great when you need to decompose a set of variables into orthogonal variables that cover the same variance, or using the first (or first few) principal component as a way of reducing the dimensionality of your predictor set (at the cost of discarding information), but it's really not a great way to create a construct.

If you specify the generate(targetvarname) option, Stata will calculate the scale and generate a new variable of the name specified in parentheses. This can be a   Dec 5, 2007 one, that would generate an “index” of intelligence: Stata has a less well- developed suite of factor analysis tools than is true of other
