Wave Er much bishop is equational
The person that knows bishop a little a little knows Robert for certain. Who is handkerchief gram, this world number one that is given to be red wine emperor judges spirits division, on century 70 time begin from an average bishop consumer, oneself founded a bishop standards of grading that makes 100 minutes, be used extensively.



Speak of Ashenfeierte (Orley Ashenfelter) reckon known person is very few, but as Princeton university economist, he founded with recursive analysis and econometric model equation of much bishop of Er of a wave explained two when why affect wine price the mainest factors faultlessly is a particular year and rank of wine place of business.



One is to be based on organic experience, one is to be based on data mining, which more accurate, somebody is becoming the possibility such research, but the vane that the wine in real life judges a grading affirmation or value. The author's viewpoint is these two kinds of methods also be immanent and mutual influence, because wine judges the home to also be met besides organic opinion to a wine,consideration a particular year and wine place of business are ranked, it is latter to former influence; And also wine judges an evaluation to must come out rank of wine place of business, it is former the influence to latter. Actually already the investigator later is like Si Hesai fining jade Tuo Jiman (Gregory Jones&Karl Storchmann) joined wine to judge a grading again on model foundation of Ashenfeierte this one variable, make whole economy evaluates model day attain perfect. Have fun at and this paper can be found on the net to reader of advanced maths self-assured fine read.



Although Ashenfeierte's model is simple, advantage dispute often understands easily, collected to 2003 1952 especially receive seasonal rainfall and summertime air temperature and price impact chart to let a person look be clear at a glance.



Following plan institute show: The abscissa is summertime air temperature from left to right increase by degrees, ordinate is to collect close period rainwater measures from the top down to decrease successively, the wine price prep above of a particular year that gules lozenge tags arrived 1952 price of average 1980 wine; The wine price of a particular year that sky-blue diamonds tags under arrived 1952 price of average 1980 wine; Did not show to the price discretion 2003 1981, the reader can try to figure according to this graph is good year which years it is off year, the big Xiaonian that judges an extent with wine again differentiates contrast.







Ashenfeierte is taught not without say 1991 he predicts complacently of Boerduo 89 with 90 a particular year it is super good year, but a lot of judge wine expert to be not agreed with at that time, now is unanimous almost: 89 with two 90 a particular year was in the past 50 years best. We also can see the trend with global heated climate here, although can have more beautiful alcoholic drink, the whole world is calefacient of brought other disaster or the attention that need everybody.
