Checking FCS Convergence

When using the fully conditional specification method, it's a good idea to check plots of the means and standard deviations by iteration and imputation for each scale dependent variable for which values are imputed in order to help assess model convergence.

  1. To create this type of chart, activate the telcoFCS dataset, and then from the menus choose:

    Graphs > Chart Builder...

  2. Select the Line gallery and choose Multiple Line.
  3. Select Months with service [tenure] as the variable to plot on the Y axis.
  4. Select Iteration Number [Iteration_] as the variable to plot on the X axis.
  5. Select Imputation Number [Imputations_] as the variable to set colors by.
