*------------------ begin example ------------------
// input the example data
clear all
input v1     str5 v115  v116   v117
      31532  "o_t1"     1.5    0.16
      31532  "o_t5"     2.0    0.87
      31532  "o_t9"     2.3    4.94
      31712  "o_t3"     4.5    2.30
      31712  "o_t1"     5.5    1.09
      31712  "o_t3"     1.4    23.09
      31712  "o_t8"     4.5    1.29
      31809  "o_t14"    4.6    1.34
      31809  "o_t1"     2.3    1.98
end

// compute the sums
bys v1    : egen v300 = total(v116)
bys v115 : egen v301 = total(v117)

// display the results
sort v1 v115
list, sepby(v1)
