WebFactor analysis is designed to find latent variables. If you want to find latent variables and cluster them, then what you are doing is correct. But you say you simply want to reduce the number of variables - that suggests principal component analysis, instead. WebThe standard command for running a regression in Stata is: regress dependent_variable independent_variables, options Clustered (Rogers) Standard Errors – One dimension To obtain Clustered (Rogers) standard errors (and OLS coefficients), use the command: regress dependent_variable independent_variables, robust cluster(cluster_variable) WebWe use the svyset command to tell Stata about the features of the sampling design that we have. In this case, we only need to specify the pweight and the FPC. svyset [pweight=pw], fpc (fpc) Next, we will use the svydes command to display the information Stata has regarding our sampling plan. shoretel contacts
