Transforms

There are a lot transforms, ranging from simple to Box-Cox. Here is a list:.

  • angular : asin( x );
  • square root : sqrt( x )
  • sqrt+0.5 : sqrt( x + 0.5 ) , for negative x
  • Reciprocal : 1.0 / x :
  • probit : (see wikipedia Probit)
  • logit : (see wikipedia Logit)
  • Z Score : x = (x - mean)/sd;
  • Box-Cox :
  • log : log( x )
  • exp : exp( x )
  • ArcSinSqr : asin( sqrt( x );
  • ArcSine : asin (x)
  • ArcSine Anscombe : asin( sqrt( ((x+ 3.0 / 8.0) / (N + 0.75)) ) )
  • aHyperbolicSine : asinh( x + 0.5);
  • abs
  • round
  • trunc
  • inch to cm
  • ºF to ºC
  • radians to º
  • º to radians
  • 24 hours to radians
  • normalise 0-1
  • 'lowes' floor(2/3 * n)
  • 'loes' floor(4/3 * n)
  • sort low to high
  • sort high to low

Transforms take a column and produce a new one with the transformed data. An easy way of getting rid of negative numbers, normalising counts, changing data for circadian analysis, or just sort.
