Equivalency of the DINA Model and a Constrained General Diagnostic
This report shows that the deterministic-input noisy-AND (DINA) model is a special case of more general compensatory diagnostic models by means of a reparameterization of the skill space and the design (Q-) matrix of item by skills associations. This reparameterization produces a compensatory model that is equivalent to the (conjunctive) DINA model, and is valid for all types of complex structu...
متن کاملMathematical Models of Interactive Computing Peter Wegner and Dina Goldin
Finite computing agents that interact with an environment are shown to be more expressive than Turing machines according to a notion of expressiveness that measures problem-solving ability and is specified by observation equivalence. Sequential interactive models of objects, agents, and embedded systems are shown to be more expressive than algorithms. Multi-agent (distributed) models of coordin...
متن کاملDNA polymerase II is encoded by the DNA damage-inducible dinA gene of Escherichia coli.
The structural gene for DNA polymerase II was cloned by using a synthetic inosine-containing oligonucleotide probe corresponding to 11 amino acids, which were determined by sequencing the amino terminus of the purified protein. The labeled oligonucleotide hybridized specifically to the lambda clone 7H9 from the Kohara collection as well as to plasmid pGW511 containing the SOS-regulated dinA gen...
متن کاملThe Sufficient and Necessary Condition for the Identifiability and Estimability of the DINA Model
Cognitive Diagnosis Models (CDMs) are useful statistical tools in cognitive diagnosis assessment. However, as many other latent variable models, the CDMs often suffer from the non-identifiability issue. This work gives the sufficient and necessary condition for the identifiability of the basic DINA model, which not only addresses the open problem in Xu and Zhang (2016, Psychomatrika, 81:625-649...
