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?
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.
