WebMar 4, 2024 · Regression analysis comes with several applications in finance. For example, the statistical method is fundamental to the Capital Asset Pricing Model (CAPM). Essentially, the CAPM equation is a model that determines the relationship between the expected return of an asset and the market risk premium. WebThe calculator above will graph and output a simple linear regression model for you, along with testing the relationship and the model equation. Keep in mind that Y is your dependent variable: the one you're ultimately interested in predicting (eg. cost of homes). X is simply a variable used to make that prediction (eq. square-footage of homes). good morning. stay safe and stay blessed https://goodnessmaker.com
