Unit Dependency Between Covariance and Correlation
Covariance and correlation are both methods for analyzing the connection between variables, but they handle unit dependence differently.
Covariance is dependent on the units of the variables.
- It is determined by multiplying the average product of each variable’s departure from the mean.
- Even if the underlying link between the variables is weak, bigger units of one variable result in higher covariance.
In contrast, correlation is unitless. It addresses the restriction of covariance through:
- Dividing covariance by the product of two variables’ standard deviations.
- The standard deviation takes into account the variable’s units of measurement.
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.
