Regression analysis is a form of predictive modelling technique which investigates the relationship between adependent(target) andindependent variable (s)(predictor). This technique is used for forecasting, time series modelling and finding thecausal effect relationshipbetween the variables. For example, r...
Regression analysis is one of the well liked statistical mechanics which is used for prediction analysis. In statistical data analysis, usually we need to begin an association between the various parameters in a data set. This association is crucial for prediction and analysis. So regression is ...
Lets take a simple example :Suppose your manager asked you to predict annual sales. There can be a hundred of factors (drivers) that affects sales. In this case, sales is yourdependent variable. Factors affecting sales areindependent variables. Regression analysis would help you to solve this p...
Regression analysis also allows us to compare the effects of variables measured on different scales, such as the effect of price changes and the number of promotional activities. These benefits help market researchers / data analysts / data scientists to eliminate and evaluate the best set of varia...
usually the first algorithms people learn in predictive modeling. Due to their popularity, a lot of analysts even end up thinking that they are the only form of regressions. The ones who are slightly more involved think that they are the most important amongst all forms of regression analysis....

Latent class analysis was performed to identify group sex types based on size, familiarity with partners, location, planning, and drug use. Associations between group sex types and sexual behaviors were evaluated using logistic regression with generalized estimating equations, employing the sample mean ...
Many financial analysis techniques involve analyzing growth rates including regression analysis, year-over-year growth, top-down analysis, such as market share percentage, or bottom-up analysis, such asrevenue driver analysis. Lastly, financial analysis often entails the use of financial metrics and ra...
There are two methods of regression analysis that use the sum of squares: The linearleast squares method The non-linear least squares method The least squares method refers to the fact that the regression function minimizes the sum of the squares of the variance from the actual data points. In...
That’s where regression tests becomes very important. Regression testing is a type of software testing that ensures recent code changes have not adversely affected existing features. It involves retesting the software after modifications to confirm that previously developed and tested functionality still...
