How many iterations did you specify? A seed will give you the set of 10 imputations that can be reproduced. But the 10 imputations should differ not identical. Can you send me the script?
Raghu
I used SRCware to create 10 imputations. I accepted the default seed (2001). Each imputation is the the same, i.e., all 10 are copies of each other. It's as if they all used the same seed. Is that the true behavior when specifying a seed? Does one have to specify no seed (and use the internal clock) to have true perturbations among the imputations? What if I want to have reproducible code that will replicate the imputations in the future-how do I specify the seed to do that?
