A model comparison approach to regression, anova, and beyond is an integrated treatment of data analysis. 1.1 overview a multiple linear regression analysis is carried out to predict the values of a dependent variable, y, given a set of p explanatory variables (x1,x2,….,xp). A rule of thumb for the sample size is that regression analysis requires at firstly, multiple linear regression needs the relationship between the independent and dependent variables to be linear. Usually, we don't have enough data at any given level of x to check whether the y's are normally distributed with constant variance, so how should this. Multiple linear regression allows you to determine the linear relationship between a dependent variable (y) and a series of independent variables (x1, x2, x3 stepwise regression analysis.
