If x × y is constant, then inversely proportional. What is the Formula for Inversely Proportional? The inverse relation formula helps in representing the inversely proportional relationship mathematically. The inverse variation formula is x × y = k or y = k/x, where x and y are two variabl...

摘要原文 In many medical studies, researchers widely use composite or long ordinal scores, that is, scores that have a large number of categories and a natural ordering often resulting from the sum of a number of short ordinal scores, to assess function or quality of life. Typically, we anal...
Children make a common error in nonstandard math equivalence problems (e.g., 2 + 3 + 4 = __ + 4) where they add up all the numbers (i.e., putting 13 in the blank) or all the numbers on the left side (i.e., putting 9 in the blank) rather than truly thinking about making...
The ARX models are linear difference equation models that characterize the relationship between the current output variable and previous values of the output and input variables. The ARX model has the form yk=−a1yk−1−a2yk−2−…−anyyk−ny+b1uk−1+b2uk−2+…+bnuuk−nu+...
This article shows how Yup'ik cosmology, epistemology, and everyday practice have implications for the teaching of school mathematics. Math in a Cultural Context (MCC) has a long–term collaborative relationship with Yup'ik elders and experienced Yup'ik teachers. Because of this long–term ethnogr...

We extend the re-parametrized NPIG2(𝜽) distribution to the corresponding regression model for investigating the relationship between the mean vector (𝜃1,𝜃2)⊤ with a set of covariates. The logit link function is adopted for 𝜃𝑗∈(0,1) with 𝑗=1,2, then the resulting model...
