What does Regression Analysis determine?

Regression analysis is a statistical method used to determine the relationships between variables. Its primary purpose in the context of security assessment and testing is to evaluate how changes, such as updates or modifications, impact the performance and operation of a system.

When conducting regression analysis, one can assess not only the positive impacts but also negative consequences that may arise from changes made to the system. This is important because understanding both the intended and unintended effects allows for a more comprehensive evaluation of the change's impact. By examining documentation and previous performance metrics, regression analysis can highlight how these changes interact with established data points, thus providing valuable insights into the operational adjustments required.

In the context of the options available, the option that highlights the assessment of changes based on documentation review aligns well with the core function of regression analysis, which seeks to identify how specific alterations may influence established performance metrics or operational behaviors. This understanding can guide future decision-making and risk management strategies effectively.
