Hey I am trying to run an EFA with 6 factors and 77 traits. Here is my script: EFA_6<-factanal(factors = 6, covmat = S_LD, n.obs = 2, rotation = "promax"). Here is the error: rror in factanal(factors = 6, covmat = S_LD, n.obs = 2, rotation = "promax") :
unable to optimize from this starting value. An EFA with 5 factors ran, with actually sensible loadings, and the CFA with 5 produced good results, but nothing more than that. Any insight would be greatly appreciated.
