Influential observations are data points that have a strong effect on the regression results. These points can significantly change the slope and intercept of the regression line and may be responsible for the appearance of outliers. Residuals and sum of squares errors are measurements used to quantify the difference between observed values and predicted values in a regression model but do not necessarily indicate influential observations.
