Factor variables converted from step 2, indexed byind1, will not have any unused factor levels. Nevertheless, factor variables fromdatmight have unused levels, which could be due to step 0 and step 1. Therefore, we need to ensure that any possible unused levels are dropped from these variabl...

Stata报道factor variables and time-series operators not allowed。我正在使用大量的控件向量,广泛应用Stata为交互提供的方法。例如:state##c.wind_speed##L.c.relative_humidity。cluster2和其他Stata包不允许将此类表达式作为自变量包含在内。是否有一种有效的方法,如何自己创建如此长的交互变量向量? 浏览15提问于...
The level indicator variables are not created in your dataset, saving lots of space. Factor variables are integrated deeply into Stata’s processing of variable lists, providing a consistent way of interacting with both estimation and postestimation commands....
I cannot install modules (I am writing code for other people and not sure what modules they have installed) Some of the regressors are factor variables. Each regression differ only by the dependent variable, so I would like to store that in the final dataset to keep track of ...
Factor and time series variables are not allowed. Differences fromlevelsof It can take avarlistand not just avarname; in that case it prints all unique combinations of the varlist. The user can specify column and row separators. It can deduplicate an arbitrary number of levels and store the...

I ran a confirmatory factor analysis in Stata using the sem command. The idea was to extract two factors: TRUST, extracted from four variables measuring the trust towards different groups of people (friends, strangers etc.) on a scale from 1 to 7; SELF-RELIANCE, extracted from four variables...
