comment:8 Changed 9 years ago by gkronber

The variable impact view should be improved.

  • Variables which are not used in any runs should not be shown
  • The significance test against mean 0 should be changed to a test if the location of the variable impact distribution of the current variable is significantly different to the location of the variable impact distribution of an unimportant variable. (The variable with the smallest average impact can be used as a reference.
  • The students t-test shouldn't be used because it is clearly not applicable (the variable impact values are not normally distributed). Instead the non-parametric Mann-Whitney-U should be used to compare the location of variables x_i and x_reference.
  • Only two-tailed tests should be used.
  • The median rank of the variable should be shown (as this is the value that is tested by Mann-Whitney-U.

Improved variable impact view with r4124

comment:12 Changed 9 years ago by gkronber

Made variable frequency analyzer more efficient and removed subtraction of base line (variable impacts are now in the range 0..1 instead of -1 .. 1) with r4125.

r4143:

  • Fixed calculation of p-values for variable impacts (the calculation procedure was implemented incorrectly because in r4121).
