Following Sargan (1983), we shall refer to this situation as a first-order underidentified case because in effect the additional parameter is locally identified but the usual rank condition for identification breaks down.
The ready identification of Down syndrome by recognition of its facial gestalt is one familiar example.
By contrast, the identification of down-regulated genes by RNA-Seq was less reliable.
There appears to be a detection bias against identification of down-regulation with microarrays, explaining the poor overlap between the three microarray data sets tested.
Identification sometimes comes down to a guess, a dim memory of a shirt worn the day a husband disappeared or of which tooth a son had lost years before in an accident.
With remarkable consistency, these residents told similar stories of facing intense scrutiny from undercover officers, of continuing to be ticketed and arrested for minor offenses, of officers sweeping through housing projects and parks, asking for identification and patting down pockets.
Mr. Singleton said the officers told everyone in the eight-room railroad apartment to gather in one area, then asked for identification and wrote down the names of those present.
But the museum is in no way dependent on regional identification or narrowed down in its focus.
In the case of Lassa virus Pinneo strain, the RPM-TEI identification narrowed it down to being one of two strains, Pinneo and Acar.
As explained in the previous section, MAUDS tackles these problems with an initial broad identification of the down states by overcrossing two moving averages, and a later refinement of the initiation and termination points by a discrete processing of the membrane potential evolution in the transition interval.
Both methods are straight forward, allowing a robust and accurate identification of bacteria down to species level.
