Analyzing large or small residuals is a crucial part of regression analysis, as it helps in identifying data points that do not fit well with the model. This can lead to the discovery of groups or patterns within the data (A), pinpointing outliers or extreme observations that may influence the model disproportionately (B), and suggesting the presence of other variables or factors affecting the relationship that were not initially considered (C). Therefore, all of these options are correct.
