Missing Values (NLR command)

Cases with missing values for any of the dependent or independent variables that are named on the [C]NLR command are excluded.

• Predicted values, but not residuals, can be calculated for cases with missing values on the dependent variable.
• [C]NLR ignores cases that have missing, negative, or zero weights. The procedure displays a warning message if it encounters any negative or zero weights at any time during its execution.
• If a variable that is used in the model program or the derivatives program is omitted from the independent variable list on the [C]NLR command, the predicted value and some or all of the derivatives may be missing for every case. If this situation happens, an error message is generated.
