Advantages and Disadvantages of Covariance
Advantages of Covariance
- Easy to Calculate: Covariance calculation doesn’t require any assumptions about the data distribution.
- Indicates Relationship: Covariance helps identify the type and direction of the relationship between variables.
- Usage in Portfolio Analysis: Covariance is useful in finance for portfolio diversification and risk management.
Disadvantages of Covariance
- Limited to Linear Relationships: Covariance only measures linear relationships between variables and does not capture non-linear associations.
- Scale Dependency: Covariance values are dependent on the scale of the variables, making it challenging to compare across different datasets.
- Doesn’t Offer Relationship Magnitude: Covariance does not provide a clear understanding of the strength of the relationship between variables.
Covariance vs Correlation: Understanding Differences and Applications
Understanding the relation between variables is seen as an essential component of Machine Learning. With covariance and correlation serving as two key concepts for quantifying this relationship. Despite being often used interchangeably, covariance and correlation have unique meanings and uses.
In this guide, we will understand the concepts of Covariance and Correlation, their differences, advantages, disadvantages, and real-world applications.
