在用bootstrap做有中介的调节效应时，在SPSS里面编写上面的这段语法，但是最后的1000维矩阵总是出不来，只有迭代之后的系数估计最优解，求助大神，不胜感激。
程序如下：
SET RNG=MT MTINDEX=54321 /*Merseene Twister random number generator, seed set at 54321*/.
MODEL PROGRAM a05=.04 aX5=.81 aZ5=-.05 aXZ5=-.14 /*Starting values for coefficients*/.
COMPUTE PRED=a05+aX5*px+aZ5*zp+aXZ5*xz /*Coefficients and independent variables*/.
CNLR ac /*CNLR procedure, dependent variable*/
/OUTFILE='E:\AA.SAV' /*File for bootstrap coefficient estimates*/
/BOOTSTRAP=1000 /*Number of bootstrap samples*/.
SET RNG=MT MTINDEX=54321 /*Merseene Twister random number generator, seed set at 54321*/.
MODEL PROGRAM b020=-.03 bX20=.28 bM20=.31 bZ20=.06 bXZ20=-.13 bMZ20=-.01 /*Starting values for coefficients*/.
COMPUTE PRED=b020+bX20*px+bM20*ac+bZ20*zp+bXZ20*xz+bMZ20*mz /*Coefficients and independent variables*/.
CNLR jx /*CNLR procedure, dependent variable*/
/OUTFILE='E:\AA.SAV' /*File for bootstrap coefficient estimates*/
/BOOTSTRAP=1000 /*Number of bootstrap samples*/.
