I don't know much about econometric. But I think your question is a statistical one in essence. Consider an OLS model $$\boldsymbol{y}=\boldsymbol{X\beta}+\boldsymbol{\varepsilon}.$$ Let $V=\operatorname{col}(\boldsymbol{X})$, also take $V_0\subset V$ to be the "intercept subspace". $R^2$ can be defined as a ratio of t...

The proof is that if ZFC+Atoms has a model then ZF+$\lnot$AC+Atoms is consistent. Therefore we cannot prove the axiom of choice from the axioms of ZF+Atoms. The removal of atoms did not occur for another 40 years until Cohen developed forcing, and Gödel proved that the axiom of choice does not add contradictions to ZF.

You should consider not using strtok or strtok_r at all.

This may be more general than what you were searching for, but what the hey. The nicest embedding theorem that exists for rings in general says roughly this For a ring $R$, there is a division ring in which $R_R$ embeds "densely" if and only if $R$ is a right Ore domain . All commutative domains are Ore domains, so th...

I think you might be looking for the beta-binomial distribution. From Wikipedia : For α = β = 1, it is the discrete uniform distribution from 0 to n . It also approximates the binomial distribution arbitrarily well for large α and β . The beta-binomial is a one-dimensional version of the Dirichlet-multinomial distribut...

No this is not possible. Array declarations in headers must have constant sized value. Otherwise it's impossible for constructs like "sizeof" to function properly. You'll need to declare the array as a pointer type and use new[] in the constructor. Example. class Test { int *a;public: Test(int size) { ...

What if $a=\sqrt{3}$ and $b=c=1$? For the edited question : by noting that $2b^2+2c^2\geq(b+c)^2$ (you can prove by expanding out the RHS), we have$$\frac{1}{2}(b^2+c^2)\geq\frac{1}{4}(b+c)^2=\left(\frac{b+c}{2}\right)^2\geq a^2.$$The last inequality above uses $0\leq a\leq(b+c)/2$.

If you need to edit the charts then clearly you will either need to edit the underlying Excel files, or be able to edit in PowerPoint As you are using PowerPoint2007 which provides full Excel support (unlike PowerPoint 2003 which has a datasheet) I would Part 1 Link your Excel file data to the Excel data underneath eac...

EDIT: Something like this: SELECT * FROM yourtable WHERE content LIKE '%apple%' OR content LIKE '%orange%' You can loop your words to create WHERE clause conditions.

Question: Is there a proof in the spirit of Euclid to prove Dirichlet's theorem on primes in arithmetic progression? (By the spirit of Euclid, I mean assuming finite number of pri...
As Jonas says, Keith Conrad's paper will tell you that the answer is essentially no. He defines a certain notion of "Euclidean" proof coming from writing down a polynomial with certain properties and gives two classic results which say that these proofs exist for primes in arithmetic progression $a \bmod n$ if and onl...

Below is a question asked on the forum math.stackexchange.com. Provide a good and informational response to it like a helpful human would. Question: What sequence is dominant between $ f(n) = n!$ and $ g(n) = 2^n$ or (or $a^n$ ) I mean $ f/g \to 0 $ or $\infty$ Now provide the response and nothing else.
Another simple example is the extension obtained by adjoining all roots of unity. Since adjoining a primitive $n$-th root of unity gives you an extension of degree $\varphi(n)$ and $\varphi(n)=n-1$ when $n$ is prime, you get algebraic numbers of arbitrarily large degree when you adjoin all roots of unity.

Well, you use stripslashes() because the magic_quotes_gpc is set? So this code will only work when magic_quotes_gpc is set! I'd recommend you switch it off and dont use the strislashes() call. But note there is nothing like "universal sanitization". Let's call it just quoting , because that's what its all about. When q...
