Study in Economics: To comprehend the relationships between different economic elements, multiple regression is a common technique in economics. To forecast the stock market index (dependent variable), a research may, for instance, utilize the GDP, unemployment rate, and inflation rate as independent factors.

For instance, the findings may indicate that, whilst the unemployment rate has a negative impact, the GDP has a significant positive influence on the stock market index
