在lisrel里面能直接输入一个协方差矩阵求出路径系数来吗（悬赏15个论坛币）

急求，在lisrel里面能直接输入一个协方差矩阵求出路径系数来吗，只有协方差矩阵和样本大小没有原始数据，程序如何写？各位大神赐教！！！

There are syntax commands

Explanation of Syntax Sections

It is advisable to adhere to the sequence of commands below.  Changing the sequence may not
always be possible for logical reasons.

Data definition

•  DA (Data) starts this line. Thereafter follows:
•  NI (Number of input variables) – number of manifest variables
•  NO (Number of objects) – sample size
•  MA (Matrix to be analyzed) – this usually is
◦  MA=CM (Covariance matrix) for a covariance matrix or
◦  MA=KM (Correlation matrix) for a correlation matrix
Note:  The matrix to be analyzed does not have to be identical with the input data
matrix (see number 3, definition of data matrix).  If desired, LISREL can internally
compute and analyze a correlation matrix even if the input data matrix contains
covariances. It can also compute and analyze covariances when a correlation matrix
is given as input (and additionally, the standard deviations of the indicator variables).

Definition of data matrix

There are three possibilities:
•  CM for a covariance matrix or
•  KM for a correlation matrix or
•  RA for raw data


Hope it helps

不错，我要试一下，不过总是提醒我有syntax error，然后提示无效之类。

大神，请问这个是哪本书里的？我去学习一下……
