The Gauss-Markov theorem states that if your linear regression model satisfies the first six classical assumptions, then ordinary least squares regression produces unbiased estimates that have the smallest variance of all possible linear estimators. The proof for this theorem goes way beyond the scope of this blog post. However, the critical point is that when you satisfy the classical.

Mean value theorem Derivative applications Differential Calculus. So this is the mean value theorem. And I have mixed feelings about the mean value theorem. It’s kind of neat, but what you’ll see is, it might not be obvious to prove, but the intuition behind it’s pretty obvious. And the reason I have mixed feelings about it, is that even.The mean value theorem (MVT) guarantees the existence of the mean value somewhere along the function, but it doesn't tell us exactly where it is. What the MVT does is replace a difference between function values, f(b) - f(a) with the derivative of the function, f'(c) times a simple difference between coordinates (b - a).Central Limit Theorem exhibits a phenomenon where the average of the sample means and standard deviations equal the population mean and standard deviation, which is extremely useful in accurately.
David Joyce’s answer is exactly the right answer to the question. I just want to expand it with an interesting case, in which, counter-intuitively, adding differentiability constraints makes the result harder rather than simpler to prove. Actually.Read More
The mean value theorem says under these conditions, there exists a number 'c' between 'a' and 'b' with what property? That ''F of b' minus 'F of a'' over 'b-a' is equal to 'F prime of c'. That's just a statement of the mean value theorem. This is always true if the conditions of the mean value theorem apply. Now all we're saying is, in this.Read More
As with the Intermediate Value Theorem and Rolle's Theorem, the conclusion of the Mean Value Theorem leaves a lot of things out. It doesn't tell us the value of c where f ' (c) equals the slope of the secant line. It doesn't tell us how many such values of c there are. All the Mean Value Theorem does is guarantee that if all the hypotheses are.Read More
What does the Central Limit Theorem tell us about the population? Close. 8.. we can take the mean from a single sample and compare it to the sampling distribution to assess the likelihood that our sample comes from the same population. In other words, we can test the hypothesis that our sample represents a population distinct from the known population.Read More
Corollaries of the Mean Value Theorem. Let’s now look at three corollaries of the Mean Value Theorem. These results have important consequences, which we use in upcoming sections. At this point, we know the derivative of any constant function is zero. The Mean Value Theorem allows us to conclude that the converse is also true.Read More
On Monday I gave a lecture on the mean value theorem in my Calculus I class. The mean value theorem says that if is a differentiable function and, then there exists a value such that. That is, the average rate of change of the function over must be achieved (as an instantaneous rate of change) at some point between and. As an example, I gave them a hypothetical means of using E-Z Passes.Read More
Proof details for direct proof of one-sided version. There is a direct proof that does not involve any appeal to the mean value theorem. This proof is shorter, but relies on the extreme value theorem.Note that the previous proof that relies on the mean value theorem indirectly relies on the extreme value theorem, whereas the proof below makes a direct appeal to the extreme value theorem.Read More

Central Limit Theorem and the Small-Sample Illusion The Central Limit Theorem has some fairly profound implications that may contradict our everyday intuition. For example, if I tell you that if you look at the rate of kidney cancer in different counties across the U.S., many of them are located in rural areas (which is true based on the public health data).Read More
