Create your account. Say a high school soccer team is likely going to win the regional championship due to strong players and a great record for the season. predict.lm produces a vector of predictions or a matrix of predictions and bounds with column names fit, lwr, and upr if interval is set. The regression line is drawn so that it ______________ the distance between itself and each of the points on the predicted (Y) variable. c. multiply to slope by the independent variable Added predictor and criterion variables should have a relationship In regression lines, one or more variables predict the value of another variable. No, it does not. b. The most common method of constructing a regression line, and the method that we will be using in this course, is the least squares method.The least squares method computes the values of the intercept and slope that make the sum of the squared residuals as small as possible. For a problem with say, 5 target variables, the leaf node would contain a vector of length 5, each representing one of the target variables. Two predictor variables are illustrated in this example: participation in sports and participation in music.
