Coefficients: (20 not defined because of singularities)
...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(): cplex6.time..sec..[cplex6.time..sec..<=0.00001]=0.00001 feature...
