Question

when regression line passes through the origin then

Answer 1

Regression through the Origin means that you purposely drop the intercept from the model. When X=0, Y must = 0. The thing to be careful about in choosing any regression model is that it fit the data well.

Answer 2

When the regression line pas.ses through the origin then the intercept is zero. (Option A)

• When you compel the intercept of linear regression to equal zero, you are doing regression through the origin.
• Fitting a model without an intercept is another term for it.
• The solution is justified by the straight-line equation y = mx + c.
• If we want the equation to go through the origin, we must set c to zero.
• As a result, when the regression line go through the origin, the intercept is zero.

Note: The question given is incomplete. The complete question is as follows;

When the regression line pas.ses through the origin then:

(a) The intercept is zero.

(b) The regression coefficient is zero.

(c) The correlation is zero.

(d) The association is zero.
