Course 5 Regression Analysis
Regression analysis is a powerful statistical method used to examine the relationship between a dependent variable and one or more independent variables. It allows researchers and analysts to model and quantify the associations between variables, make predictions, and understand underlying patterns in data. Through regression analysis, we can estimate the strength and direction of relationships, test hypotheses, and assess how changes in explanatory variables impact the outcome. This technique is widely applied across various fields, including economics, social sciences, healthcare, and engineering, providing valuable insights that drive decision-making and strategic planning.
