Probabilistic Tern
Reasoning about change requires predicting how long a proposition, having become true, will continue to be so. Lacking perfect knowledge, an agent may be constrained to believe that a proposition persists indefinitely simply because there is no way for the agent to infer a contravening proposition with certainty. In this paper, we describe a theory of causal reasoning under uncertainty. Our the...
متن کاملSTATISTICAL INTERACTION REVISITED Regina
To have valid meaning, "statistical interaction" must be consistent with biological or physical interaction which is defined as mutual (dependent) action of factors contributing to the response effect. In mathematical and statistical response models the parameter representing interaction depends on the model concerned. Factorial experiments, discrete response, and regression models are discusse...
متن کاملPlumages of the Least Tern
Over the past five years, U.S. breeding colonies of the endangered California Least Tern (Sterna albifrons browni •) have been closely monitored throughout the nesting season (Atwood et al., 1977). One result of this close scrutiny has been the observation each year of a small number of birds in prebreeding or subadult plumages (in this discussion, the term subadult is used to represent any alt...
متن کاملRegina Lectures on Fat Points
Let K be an algebraically closed field. For n ≥ 0, let An denote Kn, and let A = K[An] denote K[X1, . . . , Xn]. We refer to An as affine n-space. For any subset S ⊆ An, let I(S) ⊆ A denote the ideal of all polynomials that vanish on S. (For those familiar with Spec, the affine scheme associated to S is Spec(A/I(S)). Note that any ideal I ⊆ A defines an affine subscheme of Spec(A), and ideals I...
متن کاملNesting Success of Ohio's Endangered Common Tern
Nesting success of Ohio's endangered common tern (Sterna hirundo) population was studied during 1980 at Lucas County Port Authority Facility No. 3 (F3) located near Toledo in Maumee Bay, Lake Erie. Ninety-one clutches in three of eight tern subcolonies at this site were studied in detail. Sixty-nine percent (157/229) of the eggs failed to hatch, and abandonment of nests during incubation was re...
