在做完重插补以后，进行潜变量分析为什么会报错： Unexpected end of file reached in data file.
实在研究不出为什么了求教
代码：
data: FILE is sample1122.csv;
  variable:
      NAMES= INCODE AGE SEX RESIDE EDULEVEL BMI A1 A2;
      MISSING=ALL(999);
      USEVARIABLES= SEX RESIDE EDULEVEL  A1 A2;
      CATEGORICAL = SEX RESIDE EDULEVEL A1 A2;
  data imputation:!
        impute= SEX(C) RESIDE(c) edulevel(c) a1(c) a2(c);
        ndatasets=10;!
        save=pstdIMP*.dat;
  analysis:
   type=basic;

AND the LCA syntax is:
title: LCA sample;
data: FILE is pstdIMPlist.dat;
type=imputation;
variable:
    NAMES= INCODE AGE SEX RESIDE EDULEVEL BMI A1 A2;!最多500
    USEVARIABLES= SEX RESIDE EDULEVEL  A1 A2;
    CATEGORICAL = SEX RESIDE EDULEVEL A1 A2;
    Classes=c(2);
analysis:
type=MIXTURE;
LRTstarts=0 0 300 20;
Plot:
    type is plot3;
    series is sex(1) reside(2) edulevel(3) a1(4) a2(5);
SAVEdata:
FILE IS SAMPLE.TXT;
SAVE is cprob;
format is free;
OUTPUT: tech11 tech14;

The warning:
Unexpected end of file reached in data file.
