What type of regression is used when the dependent variable is categorical?
Logistic regression
Which regression analysis technique is used to understand the relationship between independent variables and dependent variable?
Linear regression model
What is the primary use of regression analysis in data mining?
Predicting continuous variables
Which regression technique is used when the relationship between independent and dependent variables is not linear?
Nonlinear regression
What type of regression is used for time series prediction of stock market indices?
Linear regression
Which regression technique is used to predict sales amounts of a new product based on advertising expenditure?
Linear regression
Learn about regression analysis, a technique used to predict continuous values based on other variables. This method helps in understanding relationships between independent and dependent variables, and is crucial for prediction and forecasting. Explore different types of regression models like linear, simple linear, logistic, and nonlinear regression.
