.- help for ^neigh5^ .- Generating string variable(s) specifying neighbours --------------------------------------------------- ^neigh5^ locivar locjvar [weightvar], ^gen(^newvar^)^ [ ^wgen(^newweightvar^)^ ] Description ----------- ^neigh5^ converts spatial neighbourhood information of the form locivar locjvar (optionally) weightvar ------- ------- ---------------------- 1 2 0.123 1 3 0.456 1 4 0.678 into the form locivar newvar (optionally) newweightvar ------- ------ ------------------------- 1 "2 3 4" "0.123 0.456 0.678" That is, locations 2, 3 and 4 are neighbours of location 1. (The degree of neighbourliness -- perhaps determined by distance and/or length of common boundary -- is indicated by the weights specified.) Remarks ------- ^neigh5^ is a utility for users of ^spautoc5^. It is envisaged that a data set of neighbourhood information given by two variables containing numeric identifiers will be converted to a data set containing one numeric identifier and one single string variable, for merging with a normal data file. Optionally, a numeric weight variable will also be packed into a new string variable. Options ------- ^gen(^newvar^)^ specifies a new variable to contain information. It is a required option. ^wgen(^newweightvar^)^ specifies a new variable to contain weight information. Examples -------- . ^neigh5 i j, gen(nabors)^ . ^neigh5 i j w, gen(nabors) wgen(W)^ Author ------ Nicholas J.
