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

non-numeric datum

non-numeric values are treated as missing or invalid
