spss中syntax经典程序

spss中compute生成随机数：

INPUT PROGRAM.
- LOOP #I=1 TO 1000.
-   COMPUTE Uniform_Distribution = UNIFORM(100).
-   COMPUTE Normal_Distribution = RV.NORMAL(50,25).
-   COMPUTE Poisson_Distribution = RV.POISSON(50).
-   END CASE.
- END LOOP.
- END FILE.
END INPUT PROGRAM.
FREQUENCIES VARIABLES = ALL
  /HISTOGRAM /FORMAT = NOTABLE.

spss计算字符长度并降序排列

COMPUTE strlength=LENGTH(RTRIM(stringvar)).
SORT CASES BY strlength (D).

spss电话号码用-组合

*concat_string.sps.
DATA LIST FREE /tel1 tel2 tel3 (3F4).
BEGIN DATA
111 222 3333
222 333 4444
333 444 5555
555 666  707
END DATA.
STRING telephone (A12).
COMPUTE telephone =
  CONCAT((STRING(tel1, N3)), "-",
         (STRING(tel2, N3)), "-",
         (STRING(tel3, N4))).
EXECUTE.

spss中LAG函数
COMPUTE lagvar2=LAG(var2).
EXECUTE.
COMPUTE var2=var2*2.
EXECUTE.
