To install a package in RStudio we can search for the package in the packages tab and install it or we can use R command install.packages("package name"). Packages that we use in this part are: "car", "alr3", and "faraway". There are some other tools in different packages that we can use by installing and loading those packages in our R environment. R has many of these methods in stats package which is already installed and loaded in R. Many graphical methods and numerical tests have been developed over the years for regression diagnostics. Influence: individual observations that exert undue influence on the coefficientsĬollinearity: predictors that are highly collinear, i.e., linearly related, can cause problems in estimating the regression coefficients. Model specification: The model should be properly specified (including all relevant variables, and excluding irrelevant variables)Īdditionally, there are issues that can arise during the analysis that, while strictly speaking are not assumptions of regression, are none the less, of great concern to data analysts. Technically normality is necessary only for hypothesis tests to be valid. Normality: the errors should be normally distributed. Independence: The errors associated with one observation are not correlated with the errors of any other observation Linearity: the relationships between the predictors and the outcome variable should be linear Homogeneity of variance (homoscedasticity): The error variance should be constant In particular, we will consider the following assumptions. Here will explore how you can use R to check on how well your data meet the assumptions of OLS regression. Without verifying that the data have met the assumptions underlying OLS regression, results of regression analysis may be misleading.
