IMPUTATIONSUMMARIES Subcommand (MULTIPLE IMPUTATION command)

If imputation is requested an overall imputation summary is displayed. Contents include analysis specifications and results:

  • Specifications include imputation method, number of imputations, model type for scale variables, whether two-way interactions included in models, MAXPCTMISSING setting, and analysis weight.
  • Results include imputation method, iterations (for FCS method), dependent variables imputed, dependent variables excluded from imputation, and imputation sequence.

If specified, constaints for analysis variables are also shown when imputation is requested. You can also obtain optional summaries of imputed data by specifying one or more of the following keywords. Imputation summary keywords are ignored if imputation is turned off.

MODELS Keyword

The MODELS keyword displays the imputation model for dependent variables and predictors. Imputation models are shown by default. Includes univariate model type, model effects, and number of values imputed.

DESCRIPTIVES Keyword

The DESCRIPTIVES keyword displays descriptive statistics for dependent variables for which values are imputed. Descriptive statistics are not shown by default.

  • For scale variables the descriptive statistics include mean, count, standard deviation, min, and max for the original input data (prior to imputation), imputed values (by imputation), and complete data (original and imputed values together—by imputation).
  • For categorical variables the descriptive statistics include count and percent by category for the original input data (prior to imputation), imputed values (by imputation), and complete data (original and imputed values together—by imputation).

If you specify DESCRIPTIVES, statistics are produced by default for each dependent variables for which values are imputed. You can optionally specify a list of dependent variables in parentheses. Descriptives are shown only for the requested variables. Non-analysis variables in the list are ignored.

NONE Keyword

The NONE keyword suppresses IMPUTATIONSUMMARIES output.

NONE generates an error if any other keyword is specified.
