I just recently noticed that I cannot seem to save TECH4 results anymore. It used to work for me? If I run this without the SAVEDATA command I get the TECH4 output, but when I add it, as shown below it blows up? Ideas?
TITLE: Power calculation for Intervention model
Step 1: Computing the population means
and covariance matrix
DATA: FILE IS artifica.dat;
TYPE IS MEANS COVARIANCE;
NOBSERVATIONS = 500;
VARIABLE: NAMES ARE y1-y4 x1-x5;
MODEL:
y1 on y2@.4 y3@.4 x4@.4 x5@.4;
y2 on x1@.4 x2@.4 y4@.4 x3@.4 x4@.4 x5@.4;
y3 on x4@.4 x5@.4;
y4 on x3@.4 x4@.4 x5@.4;
OUTPUT: STANDARDIZED RESIDUAL tech4;
SAVEDATA:
tech4 is t4.txt; |
|

|
|
| I don't see any latent variables in your model. Please send the input and data for the run that blows up. |
|
|
|
|
| Also, which version are you using? |

No latent variables, here is the code which I have used many times in the past:
TITLE: Power calculation for Intervention model
Step 1: Computing the population means
and covariance matrix
DATA: FILE IS artifica.dat;
TYPE IS MEANS COVARIANCE;
NOBSERVATIONS = 500;
VARIABLE: NAMES ARE y1-y4 x1-x5;
MODEL:
y1 on y2@.4 y3@.4 x4@.4 x5@.4;
y2 on x1@.4 x2@.4 y4@.4 x3@.4 x4@.4 x5@.4;
y3 on x4@.4 x5@.4;
y4 on x3@.4 x4@.4 x5@.4;
OUTPUT: STANDARDIZED RESIDUAL tech4;
SAVEDATA:
tech4 is t4.txt;
--------------
Using Version 8.2 |

Follow up:
If I remove the SAVEDATA command, I do obtain the Tech4 estimates of means and covariances in the output. I would just like to be able to write out these into a matrix using the SAVEDATA command. I have done this in the past, but now starting to question my memory, if it worked for a path structure versus a latent structure? Thanks.

The input matrix is simply(artifica.dat):
---------------------

The run stream is:

If I remove the SAVEDATA, I obtain tech4, but cannot seem to write it out ? Thanks. |

We have found a glitch in the save format. A workaround is to say
TECH4 = t4.txt;
FORMAT (TECH4) F5.3; |

Thanks so much for the work around.
