So if for any one of those parameters, let's just say B  right, let's just say that's the true distribution of  the parameter B  what you'll   you estimate O L S and you'll get  alright, you'll get biased estimates, this is what you would get from the computer, alright  so we'd be biased cos the, the true value is over here but not only that, is that, instead of having a nice peak distribution, distribution would be quite flat, alright we'd  we wouldn't have the minimum variants property  alright.
