We take the x term in one set of coordinates, subtract the mean of x from it, and multiply the difference by the analogous difference in the y term. Since there are n

Read "Econometric Theory and Methods" by Davidson and MacKinnon. The idea that the regression of y given x or x given y should be the same, is equivalent to asking if →p = →r in linear algebra terms. We know that →p is in span(→x, →b) and →r is in span(→y, →b). We known that →x ≠ c→y since this is what motivated us to look for a regression line in the first place. Regressing X on Y means that, in this case, X is the response variable and Y is the explanatory variable. So, you’re using the values of Y to predict those of X. X = a + bY. Since Y is typically the variable we use to denote the response variable, you’ll see “regressing Y on X” more frequently b = regress (y,X) returns a vector b of coefficient estimates for a multiple linear regression of the responses in vector y on the predictors in matrix X. To compute coefficient estimates for a model with a constant term (intercept), include a column of ones in the matrix X. Regression line for 50 random points in a Gaussian distribution around the line y=1.5x+2 (not shown).

So, you’re using the values of Y to predict those of X. X = a + bY Since Y is typically the variable we use to denote the response variable, you’ll see “regressing Y on X” more frequently 14 It is customary to talk about the regression of Y on X, hence the regression of weight on height in our example. The regression equation of our example is Y = -316.86 + 6.97X, where -361.86 is the intercept (a) and 6.97 is the slope (b). We could also write that weight is -316.86+6.97height. If we kept our plot as is (with x on the horizontal axis), regressing x onto y (again, using a slightly adapted version of the above equation with x and y switched) means that we would be minimizing the sum of the horizontal distances between the observed data points and the line. This sounds very similar, but is not quite the same thing.

The solution in this case is to fit a logistic regression, such that the regression line shows the estimated probability of y = 1 for a given value of x: sns . lmplot ( x = "total_bill" , y = "big_tip" , data = tips , logistic = True , y_jitter =. 03 );

Then we regress X on Y… If you run a regression of y on x, the residuals from the data you used to fit the equation have zero mean and zero correlation with x by construction. So you will get exactly zero intercept and zero slope. That’s true whether your regression fit Consider the following datasets: X1=2,8,4 X2= 0.4, 7.10, 3.2 Y= 2.6, 9.2, 5.3 a) Statistically regress Y on X1 and X2, i.e.
