I have two groups a G1 and control.  For both groups we measured their cell counts every 10 minutes:  0 to 650 min.    We are trying to find:    Difference (in cell counts) between G1 and controls - significant Effect of time (on the cell count) the same for both G1 and controls   What statistic analysis do we need to use?  One of my friends told me to use the generalized estimating equation (GEE), but I am not sure.  What is GEE used for?
I am wondering what the differences are between mixed and unmixed GLMs. For instance, in SPSS the drop down menu allows users to fit either:   analyze-&gt; generalized linear models-&gt; generalized linear models &amp; analyze-&gt; mixed models-&gt; generalized linear     Do they deal with missing values differently?    My dependent variable is binary and I have several categorical and continuous independent variables.
List of feature engineering techniques Is there any resource with a list of feature engineering techniques? A mapping of type of data, model and feature engineering technique would be a gold mine. If a matrix has orthonormal columns, they must be linearly independent, so $A^+ = (A^T A)^{−1} A^T$ . Also, the fact that its columns are orthonormal gives $A^T A = I$. Therefore,  $$A^+ = (A^T A)^{−1} A^T = (I)^{-1}A^T = A^T$$  Thus, $A^+ = A^T$. Am I correct? Thank you. Which is correct, "you and I" or "you and me"? When the phrase is used as an object, why so many native speakers are saying "you and I" instead of "you and me"? I'm not a native speaker but I thought "you and me" is correct. Not sure if this falls into the same category, but "Just between you and me" sounds more natural than "Just between you and I". So, this sounds like a stupid question I know but in the bleachverse 'names' are very important and you can only unleash the power of your zanpakuto if you can call out its name. Therefore, if a shinigami is mute, will they ever be able to achieve shikai/bankai? If so then how? Only one case that I know of is for shinigamis who have already achieved bankai to be able to release their shikais without a command.  Answers based on LN are welcome, but if you are citing from a dubious source or a source whose canon status can be question, please specifically mention it. I am mostly interested in an answer based on a  canon source. Years ago I read short story about a man sitting in his room. Suddenly appears the same man but from the future and gives him an advice about the future. Original man seems to agree to follow that advice. Man from the future goes away. Then another version of that man from another future comes and gives a completely opposite advice and begs original man to follow it. Then this second version of this man from future also left. Original man stays alone not knowing which advice from future he must follow. Can a homomorphic encryption scheme be made CCA2 Secure? Is it possible to modify a homomorphic encryption scheme so that it can be CCA2 secure?  From the definition of a homomorphic scheme, it seems that it is malleable, which would result in lack of CCA2 security. So, if we use the regular method to convert a CPA secure scheme to CCA2 secure scheme (using a hash of the message and a random value), will it still preserve its homomorphic property? Please correct me if my understanding is wrong. "Reflexive only" verbs English can use a lot of verbs in a reflexive context. Even ones that usually are used intransitively.     I laugh myself silly.   However, it seems like there are very few – perhaps no – verbs that ONLY work in a reflexive context.  Are there any? Need help identifying a comic book about a wizard I need help with identifying the comicbook, what follows is my best effort to gather whatever I remember from reading it years ago (circa year 2000, but I'm positive it was older than that):   The main character was a guy with white hair, who wanted to become powerful.  Through some training and a deal of some kind he was able to become a mage of sorts. The training was set on some other world, or possibly even parts were happening in different dimension. His powers might have had something with travelling between dimensions, but I'm not  100% sure. Also, I seem to recall there was a hard limit of how many times he could use them. Then followed a part where he was famous, but someone framed him into a scandalous plot (it was a sexual scandal, I think) using his clone or a doppelganger. At the end of the issue     the main character is seen trapped in some strange state, unable to move or escape using his powers (this might have to do something with the deal he made earlier). I remember the scene at the end as this: he is suspended in mid-air, his friends look at him in disbelief while some malevolent figure explains to them that he is now trapped forever.  His name was the title of the comic. The second and third parts were set on futuristic-looking planet.   Rings any bells? I'd like to read it again only I can't google it out.

I just found http://programmingfaq.w3ec.com/faq/4761/whats-the-hi-lo-algorithm which has an exact copy of this Stack Overflow question, , with all its answers and no difference in a single character. There is no reference to Stack Overflow.  Is this legal, or at least tolerated? Is this impertinent theft of information? I just can't see any sense in copying whole pages, particularly when not referencing the source. HTTP and HTTPS impacts on SEO I have a website http://www.domain_1.com/ hosted in a shared webserver.  I have used SSL for another website https://www.domain_2.com/ on the same server.  Due to some technical limitations (single IP), if you try https://www.domain_1.com, browser will show the same domain_2 website. But this is not a concern for me.  Question: will this scnario impact SEO of domain_1 (non-HTTPS) site? Prevent mail being marked as spam This is a  about avoiding outgoing mail being classified as spam.
