Which of the following is not true of regression analysis a. the varíables on the right hand side of a regression equation cause the varíable on the left hand side of the equation b. In multiple regression the effect of each varíable on the right hand side is hard to estimate if a variable on the right-hand-side is correlated with other variables on the right hand side c. residuals capture the random components of the variable being modelled that are not otherwise explained in the model d. Because símple regression is linear it can only be used for a straight line relationship between the variables
Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.
