Re: [cem] Fwd: cem and multiply imputed data sets from Amelia

I get the following warning messages, one for each multiply imputed dataset: Warning messages: 1: In eval(expr, envir, enclos) : non-integer #successes in a binomial glm!

2: In eval(expr, envir, enclos) : non-integer #successes in a binomial glm! 3: In eval(expr, envir, enclos) : non-integer #successes in a binomial glm! 4: In eval(expr, envir, enclos) : non-integer #successes in a binomial glm! 5: In eval(expr, envir, enclos) : non-integer #successes in a binomial glm! My dependent variable had no missing cases, so the values for it were not imputed for any observations, and I have checked that the values of it are either 0 or 1. Any ideas why I am getting this warning? I've noticed from searching online that this warning arises when weights are included in a binomial glm model, so I wonder if it might have something to do with how cem is weighting the control observations. (2) The second issue relates to displaying the output of the model. When I type: I get: Logistic model on CEM matched data: SATT point estimate: 1.509872 (p.value=0.001640) 95% conf. interval: [0.570028, 2.449717] which is fine, but when I type: I get: Treatment effect estimation for data: NULL Logistic model estimated on matched data only Coefficients: Error in symnum(pv, corr = FALSE, na = FALSE, cutpoints = c(0, 0.001, : 'x' must be between 0 and 1 Any idea why I'm getting this error?
