Null values for columns in a logistic regression analysis can adversely affect results, so Teradata Warehouse Miner ensures that listwise deletion is effectively performed with logistic regression. This ensures that any row for which one of the independent or dependent variable columns is null will be left out of computations completely. Additionally, the Recode transformation function can be used to build a new column, substituting a fixed known value for null.
