Regression analysis is commonly used in research to establish that a correlation exists between variables. Butcorrelation is not the same as causation: a relationship between two variables does not mean one causes the other to happen. Even a line in a simple linear regression that fits the data ...
This chapter provides an applied description of two key methods to evaluate the association between two research variables. First, we provide a conceptual view of the notion of non-directional linear ...doi:10.1057/978-1-137-59900-1_19Reza Norouzian...
By default, SPSS now adds a linear regression line to our scatterplot. The result is shown below.We now have some first basic answers to our research questions. R2 = 0.403 indicates that IQ accounts for some 40.3% of the variance in performance scores. That is, IQ predicts performance ...

Many software packages offer expertise in regression analysis, such as Microsoft Excel, R, and Python. Following the tutorial [3], anyone who knows Microsoft Excel basics can build a simple linear regression model. However, to interpret the regression outputs and assess the model's usefulness, ...
Testing linearity in nonparametric and semiparametric regression models through linear mixed models In most research in nonparametric and semiparametric models, the focus has been on estimation, while inference, especially hypothesis testing, has received less attention. By defining design matrices for fixed...
In this paper we consider a simple linear regression model under heteroscedasticity and nonnormality. A statistical test for testing the regression coeffic... Tan,Y W. - Communication in Statistics- Simulation and Computation 被引量: 7发表: 1986年 A Robust Approach to Heteroscedasticity, Error Seri...

In the real world, multiple linear regression is used more frequently than simple linear regression. This is mostly the case because: Multiple linear regression allows to evaluate the relationship between two variables, while controlling for the effect (i.e., removing the effect) of other variables...
