TITLE：parallel;

DATA:
  FILE IS C:\Users\zhangjun\Desktop\ZHANGJUN\LPA 5.3sav.dat;
VARIABLE:
  NAMES ARE dj jj wn protect zz xf;

USEV ARE jj zz xf dj;

ANALYSIS:
BOOTSTRAP = 5000;
ESTIMATOR = ML;

MODEL:
dj ON zz (b1);
dj ON xf (b2);
dj ON jj (c);
zz ON jj (a1);
xf ON jj (a2);

MODEL CONSTRAINT:
NEW(ind1-ind2 total r1-r2 diff);
ind1 = a1*b1;
ind2 =a 2*b2;
total = ind1 +ind2 + c;
r1 = ind1/total;
r2 = ind2/total;
diff = ind1-ind2;

OUTPUT: STAND CINT(bcbootstrap);
