Regression Toward the Mean01:52

Regression Toward the Mean

6.9K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Multiple Regression01:25

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...

Design Example: Strain Gauge Bridge or Wheatstone Bridge

988
The utilization of strain gauges as transducers for converting mechanical strain into electrical signals is a common practice in various engineering applications. These strain gauges are frequently integrated into Wheatstone bridge circuits to accurately measure parameters such as force or pressure. Within this context, each element within the circuit exhibits a resistance that undergoes subtle variations when subjected to mechanical strain. The primary objective is to convert minuscule...

Correlation and Regression00:53

Correlation and Regression

3.2K
In statistics, correlation describes the degree of association between two variables. In the subfield of linear regression, correlation is mathematically expressed by the correlation coefficient, which describes the strength and direction of the relationship between two variables. The coefficient is symbolically represented by 'r' and ranges from -1 to +1. A positive value indicates a positive correlation where the two variables move in the same direction. A negative value suggests a...

Regression Analysis01:11

Regression Analysis

8.1K
Regression analysis is a statistical tool that describes a mathematical relationship between a dependent variable and one or more independent variables.
In regression analysis, a regression equation is determined based on the line of best fit– a line that best fits the data points plotted in a graph. This line is also called the regression line. The algebraic equation for the regression line is called the regression equation. It is represented as:

Bridge rectifier01:24

Bridge rectifier

1.5K
The bridge rectifier is essential in electronics for efficiently converting alternating current (AC) to direct current (DC). Comprised of four diodes configured in a bridge layout, this rectifier effectively processes both the positive and negative halves of the AC waveform, making it superior to half-wave and full-wave center-tapped rectifiers in terms of voltage regulation and output stability.
Operationally, the bridge rectifier allows current flow through two of its diodes during each...

Area of Science:

  • Statistics
  • Machine Learning

Background:

  • Classical bridge regression offers desirable properties like sparsity but lacks systematic inference.
  • A key limitation is the absence of uncertainty estimates, hindering practical application.

Purpose of the Study:

  • To propose a Bayesian framework for bridge regression.
  • To provide uncertainty estimates for regression parameters.
  • To enable coherent inference through posterior distributions.

Main Methods:

  • Developed a Bayesian approach to bridge regression.
  • Introduced a Bayesian bridge prior.
  • Established conditions for strong posterior consistency under sparsity.

Main Results:

  • The Bayesian method provides uncertainty estimates, unlike classical point estimates.
  • Demonstrated strong posterior consistency for the Bayesian bridge prior.
  • Outperformed competing methods on simulated and real datasets.

Conclusions:

  • Bayesian bridge regression offers a flexible and statistically robust alternative.
  • The method provides valuable uncertainty quantification for enhanced inference.
  • This approach improves upon classical bridge regression's limitations.
