Parscale问题求助!!---ph2停在了一半!!

这是我写的程序:

>FILES DFNAME='fkg_mathnew.dat', SAVE;

>SAVE  PARM='FKGITEM.PAR', SCORE='FKGSUBJECT.SCO';

>INPUT NIDW=8, NTOT=26, NTEST=1, LENGTH=(26);

       (8A1,26A1)

>TEST1 TNAME=TEST1, ITEM=(1(1)26), NBLOCK=8;

>BLOCK1 BNAME=BLK1, NIT=10, NCAT=2,ORIGINAL=(0,3), MODIFIED=(1,2),

       GUESS=(2,ESTIMATE);

>BLOCK2 BNAME=BLK2, NIT=2, NCAT=3,ORIGINAL=(0,1,3), MODIFIED=(1,2,3);

>BLOCK3 BNAME=BLK3, NIT=3, NCAT=2,ORIGINAL=(0,3), MODIFIED=(1,2);

>BLOCK4 BNAME=BLK4, NIT=5, NCAT=7,ORIGINAL=(0,1,2,3,4,5,6),

       MODIFIED=(1,2,3,4,5,6,7);

>BLOCK5 BNAME=BLK5, NIT=2, NCAT=9,ORIGINAL=(0,1,2,3,4,5,6,7,8),

       MODIFIED=(1,2,3,4,5,6,7,8,9);

>BLOCK6 BNAME=BLK6, NIT=2, NCAT=10,ORIGINAL=(0,1,2,3,4,5,6,7,8,9),

       MODIFIED=(1,2,3,4,5,6,7,8,9,10);

>BLOCK7 BNAME=BLK7, NIT=1, NCAT=11,ORIGINAL=(0,1,2,3,4,5,6,7,8,9,A),

       MODIFIED=(1,2,3,4,5,6,7,8,9,10,11);

>BLOCK8 BNAME=BLK8, NIT=1, NCAT=12,ORIGINAL=(0,1,2,3,4,5,6,7,8,9,A,B),

       MODIFIED=(1,2,3,4,5,6,7,8,9,10,11,12);

>CALIB GRADED, LOGISTIC, SCALE=1.7, NQPT=31, CYCLES=8000, NEWTON=10,

       RIDGE=(20,0.5), CRIT=0.001, ITEMFIT=30, SPRIOR, GPRIOR, TPRIOR;

>SCORE EAP, NAME=TEST1, SMEAN=0.0, SSD=1.0;

PH0和PH1都是NORMAL END..

然后PH2运行到一半就停了..像这样:

[E-M CYCLES]   GRADED RESPONSE MODEL

CATEGORY AND ITEM PARAMETERS AFTER CYCLE    0

  LARGEST CHANGE=  0.000

   -2LOG LIKELIHOOD =     107986.876

CATEGORY AND ITEM PARAMETERS AFTER CYCLE    1

  LARGEST CHANGE=  1.753 (-2.893-> -1.140) at Category of Block: 8 BLK8   

   -2LOG LIKELIHOOD =     114627.083

CATEGORY AND ITEM PARAMETERS AFTER CYCLE    2

  LARGEST CHANGE=  3.875 (-0.855-> -4.730) at Location of Item: 12 0012

   -2LOG LIKELIHOOD =      88758.921

CATEGORY AND ITEM PARAMETERS AFTER CYCLE    3

   LARGEST CHANGE=  3.272 ( 3.747->  0.475) at Slope    of Item: 26 0026

然后只是弹了一个错误提示框..里面也没有写任何错误提示…

在原始数据里面重新抽了几次样都是这样…

是怎么回事呢???  要怎么解决啊!!  T^T
