  • Description
  • Computes the Quade test (non-parametric test) on EP files (.p). It allows to compare many conditions with paired subjects.
    The Quade test is a nonparametric two-way analyses of variance. It is equivalent to an ANOVA with 1 factor, paired subjects and many conditions.


  • Usage
  • epquade

This program uses an interactive input.The questions are as follows (questions (program) are italic, answers (user) are bold):
Number of conditions :
3
Number of files per condition :
10
Conover 2 by 2 comparisons : probability threshold (e.g. 0.01) :
0.01
Condition 1 | file 1 EP file name (without extension) :
epfile1cond1
Condition 1 | file 2 EP file name (without extension) :
epfile2cond1
...
Condition 2 | file 1 EP file name (without extension) :
epfile1cond2
...
Condition 3 | file 10 EP file name (without extension) :
epfile10cond3

Output file prefix for p, F and Conover values (without extension) :
quade_ep

  • Fields of parameter file and example

  • Examples

  • Comments
    1. All EP files should be compatible (in terms of number of channels and samples, number of pre-stimulus samples, sampling frequency) to the first EP file (file 1 in condition 1).
    2. In output Conover Ep files, only significant values are stored in file (positive values). The others are replaced by 1.
