    Why Collinear is Gaining Attention in the US

  • Reduced computational costs

    • Opportunities and Realistic Risks

    Collinear offers several opportunities for improvement in data analysis, such as:

  • Difficulty in identifying true relationships between variables

    • What are the best practices for dealing with collinearity?

    At its core, collinear refers to the linear relationship between two or more variables. In simple terms, it describes how variables move together in a straight line. When variables are collinear, their values change in lockstep, indicating a strong correlation between them. For instance, in a regression analysis, collinear variables may lead to unstable estimates, making it challenging to identify the true relationships between variables.
