Use the estimated equation to find the predicted value. A wildlife analyst gathered the data in the table to develop an equation to predict the weights of bears. He used WEIGHT as the dependent variable and CHEST, LENGTH, and SEX as the independent variables. For SEX, he used male = 1 and female = 2.

Example 2: Find the predicted value for the number of viewers (in millions) given that the salary (in million of dollars) of television star is $16 million. How does the predicted value compare to actual number of viewers, which was 24 million? The regression equation is. Viewers = 6.76 - 0.0111 Salary

between an observed observation and a predicted or fit value. Graphically, it is the vertical distance between a point and the line of best fit. It is found by subtracting the fitted -value from the observed y-value: An . outlier, in the regression sense, is a value with a large, in absolute value, residual.
