How do I identify in my output the parameter that has a problem? i.e.
THE STANDARD ERRORS OF THE MODEL PARAMETER ESTIMATES COULD NOT BE COMPUTED. THE MODEL MAY NOT BE IDENTIFIED. CHECK YOUR MODEL.
PROBLEM INVOLVING PARAMETER 310. Is there a sequence, so that I should go through the output, starting with loadings first, then structural parameters, correlated errors, variances, etc until I reach this number?
Thanks |

| If you ask for TECH1 in the OUTPUT command, you will see what parameter corresponds to the number 310. |

| I'm doing a multiple group SEM and I want all parameters in my model to be free and not equal across my two groups. Is there a simple command for that? |
|
|
|
|
| If you have two groups, you need to mention the parameters that you want to free in one of the group-specific MODEL commands. You can copy these statement from the overall MODEL command. |

| I have an indicator in my measurement model that is behaving very strangely. There is an outlandishly high covariance with the other indicators and TECH 1 indicates a very high start value for that parameter. I have examined the variable and cannot find any coding issues or univariate distribution issues with it. I even cheated and tried to use it as the fixed parameter but that didn't work either. Any suggestions as to another set of diagnostics for it? |

|
| Is the "high covariance" a sample covariance or a model-estimated covariance? If the latter, what are the model-estimated parameters that create this covariance? |
|

|
| Sorry, a bit of delay in getting back re: my earlier post of 9/25/09. The estimated covariance between indicators under estimated sample statistics is very high (eg., over 272). |
