Quote from HoshizakiCorrect me if I'm wrong, but would the high price of legend cards be due to the fact that they are pretty much always rare? Not sure if the 'prices based on card types' was done over all of magic, or just the rares. Just curious! Great duo of articles though! Amazing work.
It's definitely interesting as a descriptive thing. Statstalk: I'd squibble about analyzing the entire range of printed cards in one go; I'd argue there are structural breaks as to how pricing works for cards from 1995 and cards from 2012. It would also make sense to treat extremely cheap cards separately, since his data is coming from online stores who must overvalue commons for transaction cost reasons. Plus, the fact that he's using cross-sectional data means he's claiming way more than he can actually say about the effect of reprints or print runs (since print runs are correlated with time). He also runs a few questionable regressions. For example, there are a lot of fishy things going on in Table 8 (if it's a regression, there's no excluded category so he's relying on gold cards to avoid collinearity, which will not be good for his estimates. If it's means or a regression that omits the constant, which would make sense given the coefficients are all positive the significance terms aren't meaningful, and you shouldn't be taking means anyway for such a skewed distribution, which is maybe why those standard errors are so huge for a regression with 18k observations), and he's not correctly interpreting his coefficients in table 9, with the closely related CMC and CCMC.
he doesn't show his equation, which makes interpreting his regression very difficult to do (the best i can guess is a regression of log price on card age?), and i can't think of a reasonable specification that gets him a 7% annual decrease from those coefficients. he also talks about inflation which doesn't make sense because he collected the prices all at the same time. he's confusing the issue of card price growth over time with the correlation of prices and a card's age. he also doesn't take into account the standard legality bump he finds elsewhere. plus his results are insignificant once you drop ABU, so :I
oh he gets the 7% by taking 4% and adding inflation. i also can't see how he's getting 4%, unless he rescaled card age to a 0-1 scale (why?) also the fact that the coefficient drops when you leave out ABU is suspicious. surely ABU cards are above-average in price? that would suggest that the line would slope down more steeply if you leave them out. did he run the regression backwards?
Quote from god childHey man you should make me a sig-avatar its the new trend. It would be great if it could reference both man's inhumanity to man and some other trends like Nike shoes and yo-yos. tia
Quote from AnniekHey could you make me something that matches my avatar in color and/or subject matter and/or mspaint-ness?
Quote from god childJudas! Gobbo please make an me avatar that chronicles clownfish's betrayal. Try to make it as offensive as possible but still able to be used on mtgsalvation.
Quote from ClownfishOne more thing gobbo: could you maybe apply a little Zalgo to the avatar to spice it up or something?
Quote from Clownfish+ possibly an avatar about any hexapedal member of the mandibulata subphylum to match I would also appreciate if you didn't use any references to Honey, worst movie ever oh, and could you make it so the bees are disenchanted by the shortcomings of the modern system of democracy in respect to the success of populists, stagnant leadership and the political lethargy it has inspired. And maybe throw in some subtle Ukranian references. thx bro, restrictions breed creativity amirite
Quote from The Fallen Oneoh hey can you make one that is related to drama over mtg stuff
Quote from GnomeslaverI'd like one, particularly about the new rules changed to combat damage and the lack of how it stacks.
