The standard errors of the uniquenesses.
If excess kurtosis is known, provide as kurt. Standard errors are only available if the model was fit using maximum likelihood. If endog is not provided, nobs must be provided to obtain standard errors.
These are asymptotic standard errors. See Bai and Li (2012) for conditions under which the standard errors are valid.
The standard errors are only applicable to the original, unrotated maximum likelihood solution.
