I'm having trouble understanding what loggedEvents in mice mean. I don't know how to reproduce this error and I can't share my data, but don't think this is necessary.

Mice outputs LoggedEvents as a DF with 5 columns: it, imp, dep, meth and out

According to https://cran.r-project.org/web/packages/mice/mice.pdf page 143, these are

  • it iteration number at which the record was added,
  • im imputation number, dep name of the dependent variable,
  • meth imputation method used,
  • out a (possibly long) character vector with the names of the altered or removed predictors.

my question is: how do I know what the actual issue is? i have an event logged for every single column, with meth filled with "pmm" (which is my selected imputation method), while the out column in 28 out of 33 cases has the same three columns (patient age, i.e. numeric; diagnosis date, i.e. date; and finally some lab result value, numeric as well). How do I know what the problem is or what causes it?
