本人新手，在用PSM模型之后出现The balancing property is notsatisfied

Try a different specification of the propensityscore，应该怎么办？如何高效地更换解释变量使其达到满意的匹配，还有numblo( )括号中的值如何确定？万分感谢！

具体结果如下：

Step 1: Identification of the optimal number of blocks

Use option detail if you want more detailed output

******************************************************

The final number of blocks is 11

This number of blocks ensures that the mean propensity score

is not different for treated and controls in each blocks

**********************************************************

Step 2: Test of balancing property of the propensity score

Use option detail if you want more detailed output

**********************************************************

Variable married is not balanced in block 1

Variable married is not balanced in block 2

Variable longmove is not balanced in block 4

Variable nonfarmer is not balanced in block 8

Variable longmove is not balanced in block 8

Variable nonfarmer is not balanced in block 9

Variable longmove is not balanced in block 9

Variable age is not balanced in block 10

Variable married is not balanced in block 10

The balancing property is not satisfied

Try a different specification of the propensity score
