Tackle the outliers

When we have a small data set, our estimation may be sensitive to the inclusion of one or several observations. An observation is an influential observation if dropping it from the analysis changes the key estimates by a practically "large" amount.

Trimmed mean:
 In the diving game evaluation, the highest and the lowest scores are eliminated. The five remaining scores are then added up and the total score is then multiplied by the difficulty factor for each dive and then by 0.6, which gives the final result. A tie is declared when two divers get the same total score. 

Median:

Spell Check: vim tips and tricks

http://www.cs.oberlin.edu/~kuperman/help/vim/home.html

add this to your .vimrc:
if has("spell")
  " turn spelling on by default
  set spell

  " toggle spelling with F4 key
  map <F4> :set spell!<CR><Bar>:echo "Spell Check: " . strpart("OffOn", 3 * &spell, 3)<CR>

  " they were using white on white
  highlight PmenuSel ctermfg=black ctermbg=lightgray

  " limit it to just the top 10 items
  set sps=best,10                  
endif


to have a personal wordlist, make a directory called ~/.vim/spell
you can manually add things your personal wordlist (~/.vim/spell/en.latin1.add):
    printf(              (so printf is invalid, but printf( is ok)
    nextLine()
    ArrayList/=          (the /= means always match case)
    focussed/!           (the /! says treat this as a misspelling)
if you manually add to your wordlist, you need to regenerate it:
    :mkspell! ~/.vim/spell/en.latin1.add


some useful keys for spellchecking:
  ]s       - forward to misspelled/rare/wrong cap word
  [s       - backwards

  ]S       - only stop at misspellings
  [S       - in other direction

  zG       - accept spelling for this session
  zg       - accept spelling and add to personal dictionary

  zW       - treat as misspelling for this session
  zw       - treat as misspelling and add to personal dictionary

  z=       - show spelling suggestions

  :spellr  - repeat last spell replacement for all words in window

If you're so smart

The sciences, such as economics, require supposedly humanistic methods, right in the middle of their sciences; and likewise the arts and humanities require fact and logic, right in the middle of their own sciences. Newton used logic and metaphors; Darwin used facts and stories. Science is literary, requiring metaphors and stories in its daily work, and literature is scientific.
