Wolfram says NO :) http://www.wolframalpha.com/input/?i=Is+f%28x%29%3Dx%2Fsinx+continuous+over+the+reals%3F

Can we judge about continuity of function x/sinx?? Many examples in Google about sinx/x or xsinx but nothing about this function? Is there any special case? Regards

So I decided to study in details GLM. Seems very interesting and with lot of applications. Can you please suggest any prerequisites or further readings for this?

Ok I am reading this article http://www.fc.up.pt/dmat/engmat/2012/seminario/artigos2012/Luis_Ferreira/Using%20logistic%20regression%20to%20estimate%20the%20influence%20of%20accident.pdf and looking at page 734 I am trying to understand how we perform proportion test and get confidence...

I read that I can use the hypothesis testing technique for proportions to decide whether the number of levels for a design variable could be reduced. In literature the following typical test was used: Ho: pi=0 Ha: pi
\neq0 where pi is the proportion of class i (level i ) within the...

Wonder if this is true or just mistype: |x+y| \leq |x| +|y| If this is true how to proof because cannot find it out anywhere written Regards

Thank you SteamKing. But in case of not standard normal distribution smth like N(μ,σ) where both μ,σ are not equal to 0, I cannot really see smthg like -5 minutes which can be a value of simulation N(μ,σ) Any ideas about that? Regards

Hi I read at this link http://www.eecs.berkeley.edu/~aude/papers/TRB2012_stat_traffic.pdf something like bus travel times can be normally distributed. Sounds strange to me because normal distribution presumes even negative values Anything I am missing here? Regards
