mention the combination which kernel estimated densities are to be compared. If Lognormal and Birnbaum-Saunders kernel densities are to be compared along with real density then use "TLB". If Lognormal and Erlang then use "TLE". If Lognormal and Gamma to be compared then use "TLG". For Birnbaum-Saunders and Erlang use "TBE". For Birnbaum-Saunders and Gamma then use "TBG". For Erlang and Gamma use "TEG". For Lognormal, Birnbaum-Saunders and Erlang use "TLBE". For Lognormal, Birnbaum-Saunders and Gamma use "TLBG". For Birnbaum-Saunders, Erlang and Gamma use "TBEG". To compare all densities in one graph use "TLBEG".
