戸建住宅団地に居住する高齢者を中心とした世帯の犯罪不安感の決定木分析  [in Japanese] DECISION TREE ANALYSIS OF FEAR OF CRIME BY MOSTLY-OLD HOUSEHOLDS LIVING IN SUBURBAN HOUSING ESTATES  [in Japanese]

We made it clear by using decision tree analysis (CHAID) what item (kinds of anticrime measures, their costs and so on) are concerned with uneasy feeling by mostly-old household about anticrime (sneak thief, doorstep sales) living in 3 suburban housing estates developed at 30〜40 minutes by private railroad from center city 20〜40 years ago. Estimation of "anticrime performance in town" and "any suffering like sneak thief or theft" are concerned with an uneasy feeling about sneak thief. People who hear only short summary of sales or long explanation at entrance have more uneasy feeling about doorstep sales.
