Ratios in Regression, aka Questions on Kronmal Recently, randomly browsing questions triggered a memory of on off-hand comment from one of my professors a few years back warning about the usage of ratios in regression models. So I started reading up on this, leading eventually to Kronmal 1993.  I want to make sure that I'm correctly interpreting his suggestions on how to model these.   For a model with a ratio with the same denominator on both the dependent and independent side: $ Z^{-1}Y = Z^{-1}1_n\beta_0 + Z^{-1}X\beta_X + \beta_Z + Z^{-1}\epsilon $   Regress dependent ratio on the (inverse) denominator variable in addition to the other ratios Weight by the (inverse) denominator variable  For a model with dependent variable as a ratio: $ Y = \beta_0 + \beta_XX + Z1_n\alpha_0 + ZX\alpha_X + Z^{-1}\epsilon $   Regress numerator by original variables, denominator, and denominator times original variables [what about categorical variables?] Weight by (inverse) denominator  For model with only independent variable ratios: $ Y = \beta_0 + X\beta_X + Z^{-1}1_n\beta_{Z^{-1}} + W\beta_W  + Z^{-1}W\beta_{Z^{-1}W} + \epsilon $   Include numerator and (inverse) denominator as main effects, ratio as interaction term.    Are my interpretations here correct? Explicit vs implicit SQL joins Writing string at the same position using Console.Write in C# 2.0 I have a console application project in C# 2.0 that needs to write something to the screen in a while loop. I do not want the screen to scroll because using Console.Write or Console.Writeline method will keep displaying text on console screen incremently and thus it starts scrolling.  I want to have the string written at the same position. How can i do this?  Thanks I believe this to be fraud — hired, then asked to cash check and send cash as Bitcoin I have been "hired" by Nissan Motor as a key account specialist.  My first assignment is to cash two checks that I have received. Both were written by a customer who has already received the engines. The total is $2500. I am to cash the checks, get the money, take out my bonus and any other related expenses and deposit into a Bitcoin ATM. Then make copy of receipt and electronically send to my "manager".  I contacted a lawyer, was told to talk to the Department of Labor, who said they will not get involved, as this is between me and my employer. Any advice? How to set the monitor to its native resolution which is not listed in the resolutions list? After installing Ubuntu 10.04 with my Samsung SyncMaster B2030, native resolution (1600X900) is not found in the list of resolutions. Why is a Hyperplane called a "Hyper"plane? I just had this curious question. In other fields, the word "hyper" is actually used to refer to something which is "over; beyond; above" as defined by Google. An example of such terms would be Hyperglycaemia, defined by Wikipedia as:     a condition in which an excessive amount of glucose circulates in the blood plasma.   Or Hypersonic, defined by Google as:     relating to speeds of more than five times the speed of sound.   So, my question is, what would be the motive to give a Hyperplane such a name when it is defined as :     a subspace of one dimension less than its ambient space Rings and some of their properties So I am studying for an exam and was wondering if anyone could explain some of the reasoning being the proofs of the following properties:   Let R be a ring with $a,b\in R$. Then    $a0=0a=0$  $a(-b)=(-a)b=-ab$ $(-a)(-b)=ab$   Proof 1:   $a0=a(0+0)=a0+a0$ hence $a0=0$   I don't really understand why $a0+a0$ proves that $a0=0$ How do electromagnetic waves wave? Electromagnetic waves have a physical crest and trough as observed in microwaves and radio waves. I understand that is electromagnetic field vectors that wave, not the photon. But how do they wave? What does causes them to change direction? Floats appearing in wrong places Why was Hagrid's wand snapped in two when he was expelled from Hogwarts? Why was he banned from performing magic? Yes, he was expelled from Hogwarts after being framed by Tom Riddle as being responsible for Moaning Myrtle's death via Aragog the Acromantula. But why did he receive this punishment?  ‘What’ve you been feeding [the pumpkins]?’ said Harry. Hagrid looked over his shoulder to check that they were alone. ‘Well, I’ve bin givin’ them – you know – a bit o’ help.’ Harry noticed Hagrid’s flowery pink umbrella leaning against the back wall of the cabin. Harry had had reason to believe before now that this umbrella was not all it looked; in fact, he had the strong impression that Hagrid’s old school wand was concealed inside it. Hagrid wasn’t supposed to use magic. He had been expelled from Hogwarts in his third year[...] Chamber of Secrets - page 90 - Bloomsbury - chapter 7, Mudbloods and Murmurs  Why would Hagrid's wand be snapped in two and he not be allowed to do magic when:  Attendance and completion of an education at Hogwarts was not compulsory by wizarding law¹; homeschooled children were allowed to do magic for their lessons, and then do magic fully when they turned 17. The Weasley twins dropped out of Hogwarts after practically destroying parts of the castle with fireworks (and conjuring an awesome swamp on the fifth floor), yet were allowed to do magic despite not completing Hogwarts or any kind of homeschooling curriculum (that we know of). No Death Eater character that we know of was banned from using magic, despite their crimes and devotion to Voldemort. I don't recall any Death Eater wands being snapped and the owner banned from performing magic after being convicted of Death Eater crimes (please do correct me if I'm wrong). For example, Bellatrix Lestrange's wand was not snapped in Goblet of Fire when she received a life sentence in Azkaban and, as we know, her wand played a fairly significant part in Deathly Hallows.  ¹I realize in Deathly Hallows Voldemort made attendance at Hogwarts compulsory; however, by that time, Hagrid had been cleared of the charges of being responsible for Myrtle's death and was allowed to use magic again. Finding the search terms behind 'not provided' How to draw good arrows explaining parts of equation? Creation and annihilation operators in the hydrogen atom Consider an irreducible but possibly periodic Markov chain on a finite state space with transition matrix $P$. We know there exists a unique stationary distribution $\pi$. If the Markov chain were aperiodic, we would have $P^n_{ij} \to \pi(j)$ as $n \to \infty$. This fails if the chain is periodic, but we have convergence of the Cesaro averages: $$\frac{1}{n}\sum_{k=1}^n P^k_{ij} \to \pi(j) \text{ as } n \to \infty.$$ Can anyone point me to a reference that states this fact? Every reference I've seen only considers convergence for aperiodic chains, or "fixes" periodicity by considering a lazy version of the chain. Alternatively, is there a simple way to obtain this result using the result for aperiodic chains? How to differentiate formally? Why does shrinkage work? I had recently taken the hard drive out of my computer so that I could install a bigger one. But when I reconnected it to the computer, all the files on the E:\ partition and some of the files on the C:\ partition had strange names like TTv5yV5354$YVC5Wy on them. I did on one occasion move an electromagnet near the drive. Could that have caused this? Please help me, some of those files were valuable. Use of very as an adjective is (in my experience) most frequently attested in phrases like     ...the very person I was looking for.   To use adjective very with the indefinite article sounds quite bizarre in this case:     ?...a very person I was looking for.   But consider this sentence, where indefinite a is used:     Visualizing a very transformation of the master-slave relation, Thomas presses further: the slave is brother to the master, even doubly a brother.   OED treats the two uses as separate senses of the word, with the following definitions:           (first use):&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;With limitation (usually expressed by the or a possessive) to particular instances      (second use): Really or truly entitled to the name or designation   Here are two respective examples quoted in OED:     What would you say to me now, and I were your verie, verie Rosalind? (1616)   Thence we went into Queen Mary's room, and saw that beautiful portrait—that very queen and very woman. (1857)   Clearly, the difference in meaning between the two senses is quite light, and it seems to me like a kind of difference which is recurrent enough to have its own term. What is the proper term? Are there other English words having similarly related pairs of senses? And lastly, is OED jumping the gun in treating these as two senses? Could the difference in meaning instead be due to the choice of determiner?
