I got a data frame with 627 observations of 11 variables, all of them numeric (whit distinct ranges). I try to apply to it a factorial analysis with the factanal function, but occasionaly I receive the "unable to optimize from this starting value" error message. See, for instance, the following situations:

  • Try 3 or more factors, lower = 0.005

    Error message

  • Try 6 factors, lower = 0.006

    No error message. P-Value = 0.02.

  • Try 3 or 4 factor, lower = 0.006

    Error message

If I, for example, fix the number of factors at five, and start putting very low values fo the lower paramether, it will work for some particular values, but not for others (no patterns followed). I think I'll go ahead with 6 factors, but can somebody explain why this behavior?
