What is the first step to perform a regression analysis?

The first step in performing a regression analysis is defining the problem. This involves understanding the specific question or hypothesis you are trying to address with the analysis. By clearly defining the problem, you can determine what variables you need to investigate and what outcomes you are looking to predict. This foundational step sets the direction for all subsequent stages of the analysis, ensuring that the data collected, the models chosen, and the results interpreted align with the original objective of the study.

Understanding the context and objectives of the analysis helps in identifying relevant variables and formulating a well-structured approach, making this step crucial for a successful regression analysis. Once the problem is defined, you can effectively move forward with collecting data and choosing the appropriate model tailored to that specific question.
