So from our text, we know that this is true and it can be explained as follows. If we have some random data set here, we know that for a measure of our central tendency, which is another we have describing our regression line, we must pass through the mid point of our data set regardless of which direction the regression is. This is because the central tendency is at the mean in both directions, regardless of our set of data.MoreNumeradeQuestionTrue or False: The least-squares regression line always travels through the point (x̅, y̅).Answer · 1 voteAll right, guys, so the answer to this question is true.

And that's it: The regression line goes through the point (ˉx,ˉy)MoreBrainly.inQuestionthe least squares line passes through the point (x y) is called​Answer · 0 votesAnswer:It is interesting that the least squares regression line always passes through the point (`x , `y ).

The least-squares regression line is the line that makes the square of the correlation in the data as large as possible. False b. The least-squares regression line is the line that makes the sum of the squares of the vertical distances of the data points from the line as small as possible True c. The least-squares regression line is the line that best splits the data in half, with half of the points above the line and half below the line. False d. The least-squares regression line always passes through the point (x-bar,y-bar ), the means of the explanatory and response variables, respectively. TrueAnswer · 0 votesAnswer: Options A & C are False while Options B & D are true. Step-by-step explanation: The definition of least squares regression line is given as; The Least Squares Regression Line is a line that normally causes the vertical distance from the data points to the regression line to be as small as possible. The term “least squares” is derived from the fact that the best line of fit is one that minimizes the the sum of squares of the errors which is also called the variance. From this definition above, we can see that options A and C are false while option B is the perfect definition for the least line of squares. Now, the point (x-bar,y-bar ) is known as the mean. However, every least squares must pass through the middle point of the given data. The mean is the middle point of data in regression analysis. Thus, we can infer that the least-squares regression line always passes through the mean which is point (x-bar,y-bar ). Thus, option D is true.MoreCliffsNotesQuestion. Question 4 1 pts The least-squares regression line is: O at the.Answer · 0 votesAnswer of the above question is given below.Question 4)The least-squares regression line is:Answer:- The correct option is b. the line that makes the sum of the squares of the vertical distances of the data points from the line (the sum of squared residuals) as large as possible.Explanation:- The Least Squares Regression Line is the line that minimizes the sum of the residuals squared. The residual is the vertical distance between the observed point and the predicted point, and it is calculated by subtracting ˆy from y.Hence option b. the line that makes the sum of the squares of the vertical distances of the data points from the line (the sum of squared residuals) as large as possible is correct.Question 5)According to the scatter diagram, alcohol from drinking wine (in liters) is represented on x-axis, while death rate from heart disease (per 100,000 persons) is represented on y-axis.

The least squares regression line will minimize the sum of the squared distances from the data points to the straight line that passes through the data points on a scatter plot, approximating the slope of the data. I will add the caveat that a straight line may not offer as good a fit to the data as a curved line. If we venture into the world of non-linear regressions we are still safe in saying the least squared regression will be best fit. When you do multiple linear regressions, it is very easy to dump in too many variables so that your line becomes insignificant although your r^2 is nearing 1.You may also hear the term OLS which stands for Ocular Least Squares. This is a casual look at a scatter plot of the data and imagining a line that looks like a regression line. You can imagine the approximate slope and get a feel for how well a straight line will fit the data. You can even guess at an r^2 based on how tightly the scattered data clusters near your imaginary line. This g…MoreStudy.comQuestion1. A regression line, derived from the least squares method (OLS), has only two properties. True.Answer · 0 votesNO, a regression line, derived from the least-squares method (OLS), does not have only two properties.(i) The regression coefficients a^ and b^ are unbiased estimators of a and b.(ii) The sum of the residuals in any of the regression models is always calculated to be as zero, that is, ∑(Yi−Yi^)=0(iii) The sum of the observed values is equal to the sum of the fitted values of Y in a regression equation, that is, ∑i=1mYi=∑i=1mYi^(iv) The regression line derived from OLS always passes through the centroid of the data, that is, the intersection point of the two regression lines.(v) The sum of the values of the regressor variables and the corresponding residuals is zero: ∑i=1mXiri(vi) The values of the fitted values and the corresponding residuals is zero: ∑i=1mYi^riFor example, consider the following table :XYY{hat}ri=Yi-Y{hat}Xi*riY{hat}*ri81010.538-0.538-4.304-5.669444141614.0061.99427.91627.927964297.071.933.8613.64511614…More Feedback Arbor Place Foot Locker, Is the statement below true or false?
