st: which model do this commands refer to

[Walter Moturi <waltmoturi@gmail.com>]

hi statalisters!
below are some commands a friend of mine referred me to in solving a
querry i had on which dairy marketing channel was dominant among a set
of channels. The dominace was based on the net returns. The model to
which they belong to is still a puzzle although i got results. Please
may some one help me

 gen Vo1= ln( NET_RETURNS) if  OVR_allchannel==1
(133 missing values generated)

. gen Vo2= ln( NET_RETURNS) if OVR_allchannel==2
(120 missing values generated)

. gen Vo3= ln( NET_RETURNS) if  OVR_allchannel==3
(175 missing values generated)

. gen Vo4= ln(  NET_RETURNS) if  OVR_allchannel==4
(189 missing values generated)

. gen Vo5= ln( NET_RETURNS) if  OVR_allchannel==5
(194 missing values generated)

. sum  Vo1 Vo2 Vo3 Vo4 Vo5
