Decision support system
|
|---|
|
A
|
\(HI\left( 4 \right) \le HI\left( {P_{10} } \right) \le HI\left( 1 \right)\)
|
\(68.53 \le HI\left( {P_{10} } \right) \le 100\)
|
Proposed region is acceptably homogeneous
|
|
B
|
\(HI\left( 5 \right) \le HI\left( {P_{10} } \right) < HI\left( 4 \right)\)
|
\(57.62 \le HI\left( {P_{10} } \right) < 68.53\)
|
Marginal heterogeneity—reassignment of some units may be beneficial
|
|
C
|
\(HI\left( 6 \right) \le HI\left( {P_{10} } \right) < HI\left( 5 \right)\)
|
\(46.62 \le HI\left( {P_{10} } \right) < 57.62\)
|
Judgement required whether to accept homogeneous region or to reassign units to other regions to improve homogeneity of current grouping units
|
|
D
|
\(HI\left( {10} \right) \le HI\left( {P_{10} } \right) < HI\left( 6 \right)\)
|
\(0 \le HI\left( {P_{10} } \right) < 46.62\)
|
Proposed region is heterogeneous—reassignment of some units is needed
|
- HI(s): HI’s value of s equally populated deciles, s = 1, 4, 5, 6, 10
