WebLinear regression diagnostics¶. In real-life, relation between response and target variables are seldom linear. Here, we make use of outputs of statsmodels to visualise … In a regression analysis, single observations can have a strong influence on the results of the model. For example, in the plot below we can see how a single outlying data point can affect a model. We just saw that outliers are observations for which the response yiyi is unusual given the predictor xixi. In contrast, … See more One crucial assumption of the linear regression model is the linear relationship between the response and the dependent variables. We can identify non-linear relationships in the regression model residuals if the … See more It can be helpful if the residuals in the model are random, normally distributed variables with a mean of 0. This assumption means that the differences between the … See more Collinearity refers to the situation in which two or more predictor variables collinearity are closely related to one another. The presence of collinearity can pose problems in the regression … See more Another important assumption of the linear regression model is that the error terms are uncorrelated.
