001176: Perfect multicollinearity in: <value>

Description

The model shown has redundant variables that make it impossible to solve (find coefficients).

Solution

Determine which variables are telling the same story (perfect redundancy) and remove them one by one until the redundancy is gone. Other strategies for dealing with multicollinearity can be found in the Regression Analysis Basics documentation. Additional strategies for finding a properly specified regression model can be found in What they don't tell you about regression analysis.
