What is a mathematical procedure that predicts the dependent variable on the basis of knowledge known about independent variables?
regression analysis
What is the role of the stochastic error term in regression analysis?
Regression analysis is based on the assumption that the dependent variable is distributed according some function of the independent variables together with independent identically distributed random errors. If the error terms were not stochastic then some of the properties of the regression analysis are not valid.
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 regression method would be used when there is more than one independent variable?
multivariate regression
Requirements of regression analysis in statistics?
You may get more ideas from wikipedia under regression analysis. You can do a regression analysis with as little as 2 x,y points- but is it meaningful? Requirements for valid or meaningful relationships can be subjective. However, in my opinion, if meaningful relationships are to be created using regression analysis, the following are important: a) The independent variable should have values that are independent (no relation exists between them). b) There should be a good rational or experimental basis for identifying the independent variables and the resultant dependent variable. c) Sufficient data should be collected in a controlled environment to identify the relationship. d) The validity of the relationship should easy to identify both visually and by numbers (see "goodness of fit" tests).
is it possible to use primary data as independent variable and secondary data as independent variable in correlation analysis and regression analysis?
Possible maybe
Multiple regression analysis examines the relationship of several dependent variables on the independent variable?
True.
What is a mathematical procedure that predicts the dependent variable on the basis of knowledge known about independent variables?
regression analysis
What is the variation attributable to factors other than the relationship between the independent variables and the explained variable in a regression analysis is represented by?
Regression mean squares
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.
Simple regression and multiple regression?
Simple regression is used when there is one independent variable. With more independent variables, multiple regression is required.
What is the role of the stochastic error term in regression analysis?
Regression analysis is based on the assumption that the dependent variable is distributed according some function of the independent variables together with independent identically distributed random errors. If the error terms were not stochastic then some of the properties of the regression analysis are not valid.
What happens when you introduce more than one independent variable into a linear regression analysis?
this is for a class in Math-233-statistics
What does one have to do before a regression analysis?
Before undertaking regression analysis, one must decide on which variables will be analysed. Regression analysis is predicting a variable from a number of other variables.
How do I perform regression analysis in SPSS?
To perform regression analysis in SPSS: Open your dataset in SPSS. Go to "Analyze" > "Regression." Select the type of regression analysis (linear or multiple). Move the dependent variable to the "Dependent" box. Move independent variables to the "Independent(s)" box. Optionally, specify additional settings. Click "OK" to run the analysis. Interpret the results in the generated output. You can take professional help also. Experts can surely help you and assist you in performing such data analysis tasks.

What is the significance of intercept in the context of data analysis and how does it impact the interpretation of regression models?
In data analysis, the intercept in a regression model represents the value of the dependent variable when all independent variables are zero. It is significant because it helps to understand the baseline value of the dependent variable. The intercept affects the interpretation of regression models by influencing the starting point of the regression line and the overall shape of the relationship between the variables.
