The multiple regression statistical method is used to examine what relationship?

The multiple regression statistical method examines the relationship of one dependent variable (usually represented by 'Y') and one independent variable (represented by 'X').


Multiple regression analysis examines the relationship of several dependent variables on the independent variable?

True.


Simple regression and multiple regression?

Simple regression is used when there is one independent variable. With more independent variables, multiple regression is required.


What are the advantages of regression over correlation?

Correlation is a measure of association between two variables and the variables are not designated as dependent or independent. Simple regression is used to examine the relationship between one dependent and one independent variable. It goes beyond correlation by adding prediction capabilities.


What is the purpose of multiple regression analysis in statistical modeling?

Multiple regression analysis in statistical modeling is used to examine the relationship between multiple independent variables and a single dependent variable. It helps to understand how these independent variables collectively influence the dependent variable and allows for the prediction of outcomes based on the values of the independent variables.


Why are your predictions inaccurate using a linear regression model?

There are many possible reasons. Here are some of the more common ones: The underlying relationship is not be linear. The regression has very poor predictive power (coefficient of regression close to zero). The errors are not independent, identical, normally distributed. Outliers distorting regression. Calculation error.


What regression method would be used when there is more than one independent variable?

multivariate regression


What is Full Regression?

Regression :The average Linear or Non linear relationship between Variables.


What is regression analysis?

In statistics, regression analysis is a statistical process for estimating the relationships among variables. It includes many techniques for modeling and analyzing several variables, when the focus is on the relationship between a dependent variable and one or more independent variables.


What are the assumptions of cox regression?

The assumptions of cox regression are a constant relationship and the proportional hazards assumptions.


Why is it important to look at a scatter plot prior to starting a simple linear regression?

To see if there is a linear relationship between the dependent and independent variables. The relationship may not be linear but of a higher degree polynomial, exponential, logarithmic etc. In that case the variable(s) may need to be transformed before carrying out a regression. It is also important to check that the data are homoscedastic, that is to say, the error (variance) remains the same across the values that the independent variable takes. If not, a transformation may be appropriate before starting a simple linear regression.


What is the difference between simple and multiple linear regression?

I want to develop a regression model for predicting YardsAllowed as a function of Takeaways, and I need to explain the statistical signifance of the model.
