When cost is included, a reasonable strategy may often be iterating on a single model. We recommend that researchers and managers carefully examine objectives and cost when considering multimodel inference methods. Published …

"Web1 May 2024 · We are creating a new random variable d (differences), and it is important to keep the sign, whether positive or negative. We can compute d̄, the sample mean of the differences, and sd, the sample standard deviation of the differences as follows: (4.3.1) d ¯ = ∑ d i n. (4.3.2) s d = ∑ ( d − d ¯) 2 n − 1.
