  • Working on proof variance of n-1? Great. I myself try to prove that Maximum Deviation of Uniform distribution is unbaised only if MaxDev is multiplied by (n+1)/(n-1)... Numerically it absolutely agrees but to prove it is hellish work...

  • @J0EH3AD English version is ready. See my channel.

  • There is no english version of this video - yet. I am working on it.

    (n-1) is unbiased. (n) not.

  • @norwayte Is the english version ready?

  • @J0EH3AD

    English version is not ready. The summer, the heat.... and the proof needs a lot of sidesteps WITHOUT skipping anything...and I'am not a native speaker in english. It will take 40-50 minutes net. 4-5 videos. Maybe 6. I have to reconsider all the steps...because I did the german version a long time ago. A lot of work. Will see.

  • Was soll das? Das brauch' ich doch gar nicht.

  • hehe für deine videos braucht man ja nen equalizer damit die wände net so vibrieren :) nichts für ungut

  • I have been trying to find something that can proof that "n-1" is better than using "n". Is there an English verision of the video?
