How is regression analysis used in financial modeling?
In financial modeling and analysis, an analyst typically performs sensitivity analysis.

What did John Tukey say about regression analysis?
John Tukey once said, “An approximate answer to the right problem is worth a good deal more than an exact answer to an approximate problem.” That is exactly what regression analysis strives towards. It’s one of the most commonly used predictive modeling techniques that help make more informed decisions in important situations.
