 Jul21 comment Sampling 100 widgets to test for defective ones statistical inference 2nd edition exercise 3.2, the answer isn't actually in the book, I found a (apparently less than perfect) pdf of solutions online. Jul21 comment Sampling 100 widgets to test for defective ones The sampling is done without replacement since I won't be checking the same widget for defectiveness multiple times. Jul21 comment Sampling 100 widgets to test for defective ones @ClementC. the summation can go on to $100$ since as you say once it passes $100-k$ it no longer contributes anything. Jul21 comment Sampling 100 widgets to test for defective ones Yah my formula gives $k=4$ (probably accounting for the fact that $P(B) < 1$), so it's far more in agreement with your estimate. So it looks like my book is in error then, thanks.

So what you're saying is that as $|\Pi|\rightarrow 0$, $\sum_{\Pi}f(x_i)(B(x_i)-B(x_{i-1}))$ will converge to different values depending on the choice of partition sequence $\Pi$ with some positive probability? but that it will weakly converge to the same value no matter $\Pi$? Jun22 comment Why isn't the Ito integral just the Riemann-Stieltjes integral? So are you saying that the upper and lower sums will depend on the choice of the sequence of partitions? I was under the impression that that part still worked for Brownian Motion. Jun22 comment Why isn't the Ito integral just the Riemann-Stieltjes integral? But generally when we take the Ito Integral we usually imagine this extra variable of dependence as fixed right? Jun22 comment Why isn't the Ito integral just the Riemann-Stieltjes integral? You just mean not differentiable a.e.? Also don't basically all the nice properties of the Riemann Integral which don't work for the Ito integral end up following from CoV in some way or another? I mean it's all the MVT in the end. Jun22 comment Why isn't the Ito integral just the Riemann-Stieltjes integral? I know you can't apply CoV rule I said that, also if you're devonfangs I'll eat my shoe Jun22 asked Why isn't the Ito integral just the Riemann-Stieltjes integral? Jun21 comment Resources for learning mathematics for intelligent people? Seriously though what numbers mean, peano axioms, you're going in the wrong direction. Get her a book on elementary algebra/trig and tell her to do all the problems, intuition and context is built up from the inside out Jun16 asked Hedging a long position-one period Jun10 comment How did we know to invent homological algebra? I don't know any homological algebra so maybe this isn't what you're looking for. But I know looking at short exact sequences is sometimes a useful way to look at a normal subgroup of a group and the associated quotient group: $N\rightarrow G\rightarrow G/N$. Jun9 comment Factor Rings of Polynomial Rings. Could you explain how you know $\varphi$ is a homomorphism?
