Word of the Week
Week #20 - Collinearity
In regression analysis , collinearity of two variables means that strong correlation exists between them, making it difficult or impossible to estimate their individual regression coefficients reliably.
The extreme case of collinearity, where the variables are perfectly correlated, is called singularity . The Institute for Statistics Education offers an extensive glossary of statistical terms, available to all for reference and research. To celebrate the International Year of Statistics in 2013, we will provide a statistical term every week, delivered directly to your inbox.
