Multiple Comparison Tests01:13

Multiple Comparison Tests

4.4K
Multiple comparison test, abbreviated as MCT, is a post hoc analysis generally performed after comparing multiple samples with one or more tests. An MCT will help identify a significantly different sample among multiple samples or a factor among multiple factors.
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...

Multiple Regression

3.8K
Multiple regression assesses a linear relationship between one response or dependent variable and two or more independent variables. It has many practical applications.
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...

Deformation of Member under Multiple Loadings01:11

Deformation of Member under Multiple Loadings

457
When a rod is made of different materials or has various cross-sections, it must be divided into parts that meet the necessary conditions for determining the deformation. These parts are each characterized by their internal force, cross-sectional area, length, and modulus of elasticity. These parameters are then used to compute the deformation of the entire rod.
In the case of a member with a variable cross-section, the strain is not constant but depends on the position. The deformation of an...

Multiple Voltage Sources01:25

Multiple Voltage Sources

1.7K
Generally, a single battery is not enough to power some devices. In such cases, batteries can be combined in two ways: in series or in parallel.
In series, the positive terminal of one battery is connected to the negative terminal of another battery. Hence, the voltage of each battery is added to give the net voltage, which is increased because each battery boosts the electrons that enter it. The same current flows through each battery because they are connected in series.
Batteries are...

Frustration and Conflict: Approach-Approach, Approach-Avoidance01:20

Frustration and Conflict: Approach-Approach, Approach-Avoidance

502
Frustration occurs when people are obstructed or prevented from achieving a desired goal or fulfilling a perceived need. For example, when someone's input is ignored in a discussion, it can lead to feelings of frustration. Conflict, however, arises from opposing interests, goals, or actions. Conflicts can take various forms based on the nature of these opposing desires or goals.
One common type of conflict is the Approach–Approach Conflict. In this case, a person faces two desirable...

Area of Science:

  • Epidemiologic research
  • Statistical inference
  • Biostatistics

Background:

  • Multiple testing is common in epidemiology, but adjustment methods lack consensus.
  • Existing frequentist approaches to multiplicity adjustment present logical challenges and ambiguity.

Purpose of the Study:

  • To compare frequentist and Bayesian frameworks for handling multiple testing in epidemiologic research.
  • To demonstrate how Bayesian methods resolve logical difficulties inherent in frequentist multiplicity adjustments.

Main Methods:

  • Comparative analysis of frequentist and Bayesian statistical frameworks.
  • Utilizing Directed Acyclic Graphs (DAGs) to visualize and explain framework differences.
  • Conceptual argumentation regarding the logical coherence of each approach.

Main Results:

  • Frequentist frameworks exhibit logical difficulties in distinguishing relevant from irrelevant multiplicity adjustments.
  • Bayesian frameworks provide a coherent method for differentiating between relevant and irrelevant adjustments.
  • Directed Acyclic Graphs effectively illustrate these distinctions.

Conclusions:

  • The Bayesian framework offers a more logically sound and practical approach to multiplicity adjustment in epidemiology.
  • Bayesian methods provide clarity on when and how to adjust for multiple testing, unlike frequentist methods.
