Kendall tau is equivalent to the Spearman R statistic with regard to the underlying assumptions. It is also comparable in terms of its statistical power. However, Spearman R and Kendall tau are usually not identical in magnitude because their underlying logic, as well as their computational formulas are very different. Siegel and Castellan (1988) express the relationship of the two measures in terms of the inequality:More importantly, Kendall tau and Spearman R imply different interpretations: While Spearman R can be thought of as the regular Pearson product-moment correlation coefficient as computed from ranks, Kendall tau rather represents a probability.
Specifically, it is the difference between the probability that the observed data are in the same order for the two variables versus the probability that the observed data are in different orders for the two variables. Kendall (1948, 1975), Everitt (1977), and Siegel and Castellan (1988) discuss Kendall tau in greater detail. Two different variants of tau are computed, usually called taub and tauc.
These measures differ only with regard as to how tied ranks are handled. In most cases these values will be fairly similar, and when discrepancies occur, it is probably always safest to interpret the lowest value. The Gamma statistic is preferable to Spearman R or Kendall tau when the data contain many tied observations.
Thus, Gamma is basically equivalent to Kendall tau, except that ties are explicitly taken into account. Detailed discussions of the Gamma statistic can be found in Goodman and Kruskal (1954, 1959, 1963, 1972), Siegel (1956), and Siegel and Castellan (1988). Multiple response variables or multiple dichotomies often arise when summarizing survey data. The nature of such variables or factors in a table is best illustrated with examples. As part of a larger market survey, suppose you asked a sample of consumers to name their three favorite soft drinks.
Also, a wide variety of soft drinks will most likely be named. The next question is how to enter the responses into a data file. Suppose 50 different soft drinks were mentioned among all of the questionnaires. This method of coding the responses would be very tedious and "wasteful. Alternatively, we could set up three variables, and a coding scheme for the 50 soft drinks.
Then we could enter the respective codes (or alpha labels) into the three variables, in the same way that respondents wrote them down in the questionnaire. To produce a table of the number of respondents by soft drink we would now treat Resp.
Note that the counts in the first column of the table do not add up to 500, but rather to 842. For example, referring back to the sample listing of the data file shown above, the first case (Coke, Pepsi, Jolt) "contributes" three times to the frequency table, once to the category Coke, once to the category Pepsi, and once to the category Jolt.
The second and third columns in the table above report the percentages relative to the number of responses (second column) as well as respondents (third column).
Thus, the entry 8. Suppose in the above example we were only interested in Coke, Pepsi, and Sprite. As pointed out earlier, one way to code the data in that case would be as follows: COKE PEPSI SPRITE. In other words, one variable was created for each soft drink, then a value of 1 was entered into the respective variable whenever the respective drink was mentioned by the respective respondent.If the market is efficient, the intercept of this regression should be zero, the slope (beta) in this regression should be 1, so that the forward premium today is an optimal predictor of the future exchange rate change.
Also, the error term should be white noise, i. Due to the forward premium puzzle, they can, on average, buy enough of the original currency to pay off the loan and still pocket a bundle.

The "moving wall" represents the time period between the last issue available in JSTOR and the most recently published issue of a journal.
Moving walls are generally represented in years. In rare instances, a publisher has elected to have a "zero" moving wall, so their current issues are available in JSTOR shortly after publication. Note: In calculating the moving wall, the current year is not counted. For example, if the current year is 2008 and a journal has a 5 year moving wall, articles from the year 2002 are available.

So much so, that hybrid array sales are faltering and arrays made solely with hard disk drives (HDDs) are all but disappearing. Gartner analyst Valdis Filks believes that solid-state arrays (SSAs) will improve in performance by a factor of 10, and double in density and cost-effectiveness within the next year. This is destined to change the dynamics of the storage market. And from there, he sees many years of further expansion.However, as with any quarterback, his MVP chances are directly tied to how well the Raiders play.
If they take a step back and miss the playoffs, Carr will undoubtedly shoulder some of the blame. Nevertheless, his price is tough to pass up. Ryan was worthy of his 2016 victory, but he kinda sorta won by default. The Falcons offense is poised to take a step back in 2017, so avoiding Matty Ice just makes sense.
If the Bucs make a playoff charge, Winston will be the reason.
He is still prone to poor decision-making, but his arm talent and fearless attitude are attributes needed in a franchise quarterback. The fact that his odds are on par with Ryan and Carr is proof that his star is rising in the eyes of oddsmakers.
No Zeke Elliott means more passing attempts for Dak. That could be good, or it could be bad. Make no mistake about it, Prescott was impressive as a rookie. But a much tougher schedule and no Zeke to help alleviate pressure opens up the possibility of more errors in judgement for the second-year signal caller. A lot will have to go right for Dak to enter the MVP conversation.
DJ will need to rush for over 2000 yards and score 18 touchdowns to have a legit shot. And the Cards will have to make the playoffs. Could all that happen. Like Winston, Mariota passes the eyeball test. Any run the Titans might make in 2017 will be due to his superb play. Because quarterbacks dominate MVP races, he should not be overlooked. Newton was not good in 2016. And look at this price. Way back in the year 2000 a sophomore Eagles quarterback named Donovan McNabb finished second in MVP voting.
Could history repeat itself in 2017. Toss a C-note down and become legend. Not since Lawrence Taylor in 1986 has a defensive player seized the MVP. JJ Watt and Von Miller have been in the conversation in recent years. Perhaps this is the year a stud pass rusher crashes the QB party. Mack is an absolute monster and definitely worth a flier. Probably somewhere in between. It will be interesting to see how the Panthers utilize their dual-threat rookie.
Will Cam stop running and check-down more. How will the carries be split between McCaffery and Jonathan Stewart.Thank you for making our holiday very memorable. Brian, United States South and West in Detail, August 2016 We had an amazing experience from start to finish. We worked with three travel advisors, and received great responses and support from each. We planned our trip rather quickly (booked late July and traveled late August) but the team was able to put together a great experience and a great intro to Iceland.
From the car, to the hotel selections, to the activities, we got a wonderful introduction to Iceland and cannot wait for a return trip.

I liked your flexibility in making modifications to existing tours, your willingness to reserve a car and your knowledge of local train and bus schedules. Amanda, United States The Natural Wonders of Iceland, July 2016 Our tour guides we awesome.
The lady that did our city tour was well informed and kept the kids entertained. After that tour, I was looking for street art whenever we walked somewhere. Our tour guide that we had for the golden city tour was well versed and loved her job. Throughout the whole experience, I never had a bad customer service experience and welcomed by all. We were a bit bummed that it snowed the second day, but that only last a little bit. Since moving to the UK the kids haven't seen snow, so it was fun to have a snowball fight.
Thanks for everything, the trip was grand. Renee, United States The Natural Wonders of Iceland, July 2016 Anita was great. She set up our itinerary and had things lined up and answered all my questions promptly and efficiently.
Tour guide was awesome. I cannot praise her highly enough. She was highly professional, and still warm, personable, friendly, incredibly knowledgeable and handled a diverse group beautifully. The greenhouse was fascinating. And, I thought the addition of a few hours at a local farmer's home was the icing on the cake. We got to meet a farmer and his family and get a sense of what life is like for them. I was sorry to leave and want to come back.
Alan, United Kingdom Majestic Highlights of Norway, July 2016 Despite the weather this was a thoroughly enjoyable holiday.
