Para 2.1.20 — MSO (Audit)
Original Rule Text
2.1.20 Regression analysis: This is a statistical technique that creates an equation to reveal how one variable is related to one or more other variables. It is similar in principle to predictive analysis but has added mathematical rigor and objectivity. It is generally used in the execution stage. It requires understanding of the statistics of complex variables and is therefore not “user-friendly” to the general auditor. It also requires much time for application and testing and is therefore mostly used infrequently.
What This Means
Regression analysis is a statistical technique that mathematically models how one variable relates to others. It is similar to predictive analysis but more rigorous and objective because it uses statistical equations rather than manual estimates. However, it requires specialized statistical knowledge, takes significant time to set up and test, and is therefore used infrequently in routine audits.

- 6Used infrequently due to complexity and resource requirements
Practical Example
The CAG's performance audit wing uses regression analysis to model the relationship between rainfall, canal water availability, and agricultural yield in an irrigation project. The model shows that despite adequate water supply, yields in certain districts are unexpectedly low — pointing to possible diversion of irrigation water or poor maintenance of distribution channels.
