Microsoft Excel is a spreadsheet editor developed by Microsoft for Windows, macOS, Android, iOS and iPadOS.It features calculation or computation capabilities, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications (VBA).
In statistics, the two-way analysis of variance (ANOVA) is an extension of the one-way ANOVA that examines the influence of two different categorical independent variables on one continuous dependent variable. The two-way ANOVA not only aims at assessing the main effect of each independent variable but also if there is any interaction between them.
In linear models, there are two main requirements for using IVs: The instrument must be correlated with the endogenous explanatory variables, conditionally on the other covariates. If this correlation is strong, then the instrument is said to have a strong first stage. A weak correlation may provide misleading inferences about parameter ...
The algorithm considers two problems: the master problem and the subproblem. The master problem is the original problem with only a subset of variables being considered. The subproblem is a new problem created to identify an improving variable (i.e. which can improve the objective function of the master problem).
A normal chest X-ray after placement of an ICD, showing the ICD generator in the upper left chest and the ICD lead in the right ventricle of the heart. Note the 2 opaque coils along the ICD lead. The process of implantation of an ICD system is similar to implantation of an artificial pacemaker. In fact, ICDs are composed of an ICD generator and ...
An engine-generator is the combination of an electrical generator and an engine (prime mover) mounted together to form a single piece of self-contained equipment. The engines used are usually piston engines, but gas turbines can also be used, and there are even hybrid diesel-gas units, called dual-fuel units.
In Australia, credit scoring is widely accepted as the primary method of assessing creditworthiness. Credit scoring is used not only to determine whether credit should be approved to an applicant, but for credit scoring in the setting of credit limits on credit or store cards, in behavioral modelling such as collections scoring, and also in the pre-approval of additional credit to a company's ...
If we set = in the above equation, we get the pure shear Hoek–Brown criterion: = [+] The two values of are unsymmetric with respect to the axis in the -plane.This feature of the Hoek–Brown criterion appears unphysical [2] and care must be exercised when using this criterion in numerical simulations.
