st: Identify 5 closest observations of a variable and then calculate average of another variable based on the observations identified |

Dear Statalisters, The data below shows three variables:- region, var1 and var2. For each observation in a given region, I want the 5 closest observations based on var1 (not counting the observation in question). I basically need the average value of var2 for the 5 observations that are identified. I don't have any missing values in my data for all three variables below. I can also confirm that I have a few regions with less than 6 observations each; hence these regions will be ignored. I am using Stata 12. Thanks, Joe region var1 var2 A 3.29515 47 A 5.39742 38 A 7.94641 43 A 11.25495 235 A 22.35908 61 A 27.19206 76 A 41.03306 66 A 45.56846 89 A 53.63861 116 A 73.2925 76 A 104.3025 63 A 229.7772 74 A 634.0973 61 A 1053.78 80 A 1163.681 47 B 2.339128 55 B 2.378151 46 B 9.831361 47 B 15.83442 57 B 16.48956 42 B 28.70144 44 B 56.01777 29 B 113.9736 103 B 178.731 47 B 340.715 103 C 0.5892565 44 C 2.016974 37 C 3.041719 76 C 4.009228 80 C 5.856674 51 C 7.587287 188 C 8.827202 66 C 11.53763 48 C 11.67932 152 C 11.86612 51 C 12.95344 84 C 14.85097 63 C 17.12918 47 C 17.74263 67 C 17.97567 75 C 20.60005 84 C 22.13938 44 C 28.99966 44 C 31.23538 55 C 31.52542 36 * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
