[FieldTrip] ft_statfun_depsamplesFunivariate

[Schoffelen, J.M. (Jan Mathijs)]

Hi Elisa,

To follow up on my previous message: the drop-in replacement of the tcdf function was taken from octave, perhaps a similar function exists for fcdf. If you manage to find one on the web, you can add this to your version of fieldtrip, and create a pull request on github (PR) so that it will also be made available to the rest of us. Thanks in advance! The requirement of such a drop in replacement should be that it has the same functionality as the matlab version, including its API (input and output arguments).

Best wishes,
Jan-Mathijs

Good morning/evening,

I am trying to compute an Univariate ANOVA with 3 repeated measure levels and I get the following error:


Undefined function or variable 'fcdf'.

Error in ft_statfun_depsamplesFunivariate (line 181)
    s.prob = 1-fcdf(s.stat,s.dfnum,s.dfdenom);

Error in ft_statistics_montecarlo (line 267)
  [statobs, cfg] = statfun(cfg, dat, design);

Error in ft_freqstatistics (line 193)
  [stat, cfg] = statmethod(cfg, dat, design);



I checked both the Fieldtrip and Matlab functions folder and I could not find the fcdf function (only the Student's T cumulative distribution function, tcdf).
Has anyone had this issue?


Thank you for your attention.

Best wishes.

Elisa
