"Simpson's paradox, or the Yule–Simpson effect, is a paradox in probability and statistics, in which a trend that appears in different groups of data disappears or reverses when these groups are combined. It is sometimes given the impersonal title reversal paradox or amalgamation paradox.[1] This result is often encountered in social-science and medical-science statistics,[2] and is particularly confounding when frequency data are unduly given causal interpretations.[3] Simpson's paradox disappears when causal relations are brought into consideration. Many statisticians believe that the mainstream public should be informed of the counter-intuitive results in statistics such as Simpson's paradox." -- Super interesting. The Berkeley 1973 sexism lawsuit is a perfect example to understand this. #statistics #paradox #probability #science #data #bias #contrary_to_common_sense #@references #@memorize #interesting #from #delicious #pub

pretty ugly and barely any point. just creates an ugly pie chart of your top 25 artists. #last.fm #data #web_tools #tools #linkbait #analysis #music #fun #not_good #ideas #pub

"Last.fm tool: Create your personal Last.fm user tag cloud" #last.fm #data #web_tools #tools #analysis #music #linkbait #fun #ideas #pub

"With the form below, you can compare two Last.fm users, based on their personal musical tag clouds. This approach is different from the approach used by Last.fm, where users in the population are compared based on the common artists in their playlist. We feel that tag clouds give a better interpretation of musical preferences than other methods (compare Last.fm's own Taste-o-meter), as more descriptive meaning is embedded in tags (like, genres), rather than (often unknown) artists. The script also shows important differences among the tag clouds." #last.fm #data #web_tools #tools #toread #pub

"Last.fm tool: Level 2 of the musical eclectic test! The following script takes the 50 top artists in your musical profile from Last.fm, and finds the collection of top 20 similar artists (where the artist itself is the #1 most similar artist) for this top 50. The resulting is a list of artists similar to your preferred artists. As the list is larger (maximum = 1000), your musical preference is more diverse. As a result, with this test it is harder to get a high score, as compared to the original eclectic test. And because this score goes up to 1000 (and not to confuse it with the orginal "eclectic score"), this test is the "super-eclectic" test!" #web_tools #data #last.fm #linkbait #tools #music #fun #analysis #ideas #pub

"The long and short tail are the percentage of the total amount of tracks played that fall outside and respectivly inside the cummulative tracks played for the top-n rated artists. The short tail is exactly the oposite. If that's to much to grasp at once: To calculate the Long Tail you take a user's Top50. Calculate the sum of all the playcounts in there. Then divide it by the total amount of tracks played as listed in the user description area. Multiply it by a hundred to get a percentage. Substract it from a hundred to get the short tail. Based on a idea by itazurada. AEP is the is the brainchild of C26000, he wrote a nice journal about AEP calculation." #web_tools #data #linkbait #analysis #tools #last.fm #music #fun #ideas #pub

"he other day I was looking at the audioscrobbler (the core, the data supply of last.fm) web services for interesting feeds and I saw the week chart feeds. I noticed that they provide a list of all available weeks and quickly realized that you could combine this with the Top50 feed to reconstruct older Top50's. Just subtract an artists play count from next week's total play count and you have the current total play count. So I went to work and produced code to perform different task. Collect the Top50, collect all week stats, compare the two and reconstruct a history. This was going goooood. Yeah. Then I took a pencil and made a drawing of what the chart should look like and I loved it. So I created the greatest spaghetti of variables I'd ever seen and uploaded the new script. It was just shock and awe! Except for a syntax error or two It all worked and the output was just as I'd hoped it'd be, except that... The 50 black lines in this tiny little graph were just such a mess, you could never make up what was what. Damn (that spaghetti again)! I went back to work and added many features, a lot of color to the lines, auto scaling (1px = 1play), a legend in the color of the line and a line that connects the chart-line to the legend and a function to unclutter the legend for artist with the same or almost the same play count (which in turn made the lines harder to interpret but being able to read the legend outweighs clear lines :-P though I'm still looking to solve this...)" #web_tools #data #linkbait #last.fm #tools #music #fun #analysis #ideas #pub

Random stats like playcount, unique tracks, averages for different time periods, top periods of various times, most consecutive tracks/artists, total play time. And the pic they provide gets auto updated too. #web_tools #data #last.fm #analysis #tools #music #fun #linkbait #stats #ideas #favs #pub
