Hi,
If I want to find the least squares estimator of the slope of a simple
linear regression model where my intercept is known, will this
estimator will be the same as if I did not know my intercept(=Sxy/sxx)?
How about the variance and the confidence interval of my estimator?
will they be bigger or smaller than the estimator for the case where
both my intercept and slope unknown?
Thank you for your help.
