In a simple linear regression, if we scale the data by a negative number, does the t-statistic for the slope change to be the negative of the original result and the p-value for the slope change because the t-statistic for the slope changes?

Expert Solution

As it is given data so assuming that both X and Y are scale by negative so,

As we have seen is not effected so t statistics doesn't change and p value also doesn't change.

But alpha becomes negative but t statistics is depend on beta( slope parameter) so it doesn't change.

Please upvote if i'm able to help you it means a lot

When we estimate a linear multiple regression model (including a linear simple regression model), it appears that the calculation of the coefficient of determination, R2, for this model can be accomplished by using the squared sample correlation coefficient between the original values and the predicted values of the dependent variable of this model. Is this statement true? If yes, why? If not, why not? Please use either matrix algebra or algebra to support your reasoning.

Consider the simple linear regression mode

Consider the simple linear regression modelYi = β0 + β1xi + εi, where the errors εi are identically and independently distributed as N (0, σ2).(a) If the predictors satisfy x ̄ = 0, show that the least squares estimates βˆ0 and βˆ1 are independently distributed.(b) Let r be the sample correlation coefficient between the predictor and response. Under what conditions will we have βˆ1 = r?(c) Suppose that βˆ1 = r, as in part b), but make no assumptions on...
