The technical-necessity conjecture for restrictions in additive quantile backfitting
Technical-necessity conjecture. Both the requirement of consistent initial estimators and the restriction on the number of iteration steps are necessary only for technical reasons…

OR's weak-condition convergence conjecture for backfitting algorithms
Consider the additive model … with $E(\varepsilon\mid U,V)=0$ almost surely, and estimate its component functions by backfitting, using kernel smoothing. OR's convergence conjectur…
