Hello,
I am trying to run a linear regression analysis on my data set. For some
reason most variables are removed due to singularities.
My linear regression looks this way (I am using only partial data, which
is selected by flags):
fm<-lm(log(cplex6.time..sec..[flags]) ~ cplex6.cities[flags] +
log(1/features.meanOver.frust[flags]) +
log(1/features.meanOver.minDist[flags]) +
[...]
avg..steps.to.loc..Opt..norm..[flags] + NN.List.opt..tour.max.[flags])
As I am using inversion and logarithms I set all data to positiv values,
before running lm(...
