Query to monitor matching of data to models = No |
Specifying Query=Yes in your specification file or from the "Estimation" menu causes Facets to report the decisions it makes in the matching process for each datum.
When Query=Yes is in effect, the following is displayed on the screen:
Query=Y in effect! Data matching displayed:
Then, for each data point a message is displayed,
press Ctrl+Z to continue.
press Ctrl+Q to cancel Query=Y operation.
Query=Y: Message |
Meaning |
datum: 1,1,0 |
The precise Facets-format data element to be matched to a model |
blank |
The entire data line is blank, or commented out with ;
|
replications less than 1 |
The datum looks like R0,1,1,0 with a replication of 0. So the datum is not used. |
datum matched model: _ |
Matching was successful. In this case, the datum matched the first model specified. |
match with "?" failed for element _ in facet _ of model _ |
Matching to this model failed. |
no matching model - datum ignored |
Datum matched no model |
unspecified element: _____ in facet: _ |
Datum contained an element not specified in Labels=, and so datum is bypassed. |
no datum value - datum ignored |
The datum value was blank, and so this datum is bypassed, e.g, ,, in a string of data elements. |
model is Missing |
Datum treated as missing, and so ignored. |
data recoded to ___ |
Datum has been given a new value |
negative datum |
negative values are treated as missing |
