This article reviews eight different software packages for lin-
ear structural equation modeling. The eight packages—Amos,
SAS PROC CALIS, R packages sem, lavaan, OpenMx,
LISREL, EQS, andMplus—can help users estimate parameters
for a model where the structure is well speciﬁed. Capabilities
for handling single group, multiple group, nonnormal variables,
and missing data are considered and the eight packages are
compared across a variety of criteria from documentation to pa-
rameter estimation. The main difference between the packages
is the presence of a graphical interface for model speciﬁcation
and presentation of results. Each package differs in terms of
strengths, areas of improvement, and unique features that may
dictate the choice of selection. Some suggestions on areas of
improvement for all software packages are made. This article
has supplementary materials online.

KEY WORDS: Analysis of moment structures; Conﬁrmatory
factor analysis; Covariance structure analysis; Latent variable
modeling; Linear structural relations; Path analysis.

hi,

HTH means Hope This Helpful:)

你试试把这个两个东西去掉：

bseed=79566;
chains=1;

我猜你电脑应该有两个核吧。再加上一句proccessors=2；

谢谢HTH的解惑！

不过我把 type=basic 改成 type=general 了之后，仍然存在问题，运行结果提示：

*** WARNING in MODEL command
All variables are uncorrelated with all other variables in the model.
Check that this is what is intended.
1 WARNING(S) FOUND IN THE INPUT INSTRUCTIONS

*** FATAL ERROR
   THERE IS NOT ENOUGH MEMORY SPACE TO RUN Mplus ON THE CURRENT
   INPUT FILE. YOU CAN TRY TO FREE UP SOME MEMORY BY CLOSING OTHER
   APPLICATIONS THAT ARE CURRENTLY RUNNING. NOTE THAT THE MODEL MAY
   REQUIRE MORE MEMORY THAN ALLOWED BY THE OPERATING SYSTEM.
   REFER TO SYSTEM REQUIREMENTS AT www.statmodel.com FOR MORE
   INFORMATION ABOUT THIS LIMIT.

模型每次运行到m=20的时候就意外停止了，请问，这是内存不足的问题？还是语句的问题？

谢谢~~

hi,

采用auxiliary variable impute缺失值的时候，type=general。详见手册p497. type=basic只是将auxiliary variable保留在数据文件中做后续分析只用，并不采用他们impute缺失值。

auxiliary variable的用法一共有四种。详见手册p496.

各位好！

请问有没有人用过多重插补法进行缺失值处理的？我试过，第一步就出现了问题，请教一下高手解答！

下面是Mplus的语句：

INPUT INSTRUCTIONS

data:file =suzhou with missing.txt;
variable:
name=y1-y17 i1-i5 gender age;
usevariables=y1-y17;
missing=all(9);
auxiliary=(m)gender age;
data imputation:
impute=y1-y17;
ndatasets=20;
save=suzhouimp*.dat;
analysis:
type=basic;
bseed=79566;
chains=1;

*** ERROR in VARIABLE command
The 'm' specifier in the AUXILIARY option is not available for TYPE=BASIC.

是type=basic不对么？去掉之后又有问题：

*** WARNING in MODEL command
All variables are uncorrelated with all other variables in the model.
Check that this is what is intended.
   1 WARNING(S) FOUND IN THE INPUT INSTRUCTIONS

*** FATAL ERROR
   THERE IS NOT ENOUGH MEMORY SPACE TO RUN Mplus ON THE CURRENT
   INPUT FILE. YOU CAN TRY TO FREE UP SOME MEMORY BY CLOSING OTHER
   APPLICATIONS THAT ARE CURRENTLY RUNNING. NOTE THAT THE MODEL MAY
   REQUIRE MORE MEMORY THAN ALLOWED BY THE OPERATING SYSTEM.

说是内存不够？到底怎么回事呢？盼请高手解答！！
