How are Positive and Normative economics different from each other? - Positive economics clearly states and economic issue, and normative economics provides the value-based solution for the issue. What are factors of production? - The resources the economy has available to produce goods and services How can Labor's contribution to an economy's output of goods and services be increased? - By increasing either the quantity of labor of human capital. What are two keys to the use of an econ...

Least Square Elimination (LSE) cannot be applied to GLM models. - False - it is applicable but does not use data distribution information fully. In multiple linear regression with idd and equal variance, the least squares estimation of regression coefficients are always unbiased. - True - the least squares estimates are BLUE (Best Linear Unbiased Estimates) in multiple linear regression. Maximum Likelihood Estimation is not applicable for simple linear regression and multiple linear regres...

second degree equations - ANSWER -solved by factoring or the quadratic formula absolute value - ANSWER -equivalent to two equations without the absolute value sign > e.g. |x + 3| = 7 → +(x + 3) = 7 or -(x + 3) = 7 solving linear inequalities - ANSWER -can be treated like a linear equation, however, when multiplying or dividing both sides of an inequality by negative numbers requires the inequality sign to be reversed solving absolute value inequalities - ANSWER -- with absolute va...

Algorithm - At its core, an algorithm is really just a generalized, conceptual solution to a problem that can later be implemented in some real-world form like a computer program. Application Program Interface - Application program interface (API) is a set of routines, protocols, and tools for constructing software applications. An API specifies how software components should interact. In addition, APIs are used when programming graphical user interface (GUI) components. Binary - A numeric ...
