Dear Dr. Muthèn,
I am running a model X --> y --> u --> z.
x, y, and z are continuous variables. u is a binary variable with a distribution of 15/85. Is there a possibility to correct for a basrate of 50/50 in Mplus? |

| Perhaps you are thinking of some sort of poststratification adjustment using weights. I don't know how that would be done in this case. |

Is there a possibility to correct the correlation matrix by hand or to impute a corrected correlation matrix?
If I use the weighting option would you use the weight or frequency weigth option?
Would you weight the low probability cases in the 15/85 distribution with a weighting factor of 5.66 and the other cases with a weighting factor of 1? |
