Regression Toward the Mean01:52

Regression Toward the Mean

7.0K
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

4.0K
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...

Poisson's Ratio01:23

Poisson's Ratio

1.1K
Poisson's ratio is a material property that indicates their stress response. It explains the connection between the elongation or compression a material undergoes in the direction of an applied force and the contraction or expansion it experiences perpendicular to that force. When a slender bar is loaded axially, it stretches in the direction of the force and contracts laterally. Poisson's ratio is the negative ratio of this lateral contraction to the axial elongation. The negative sign...

Correlation and Regression00:53

Correlation and Regression

3.4K
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

8.4K
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:

Understanding the Self01:28

Understanding the Self

303
The self is a central aspect of human identity, encompassing an individual’s beliefs, emotions, perceptions, and experiences. It is a cognitive and psychological construct that enables individuals to interpret their traits and behaviors, influencing how they perceive themselves and interact with the world. While personality consists of stable and enduring characteristics, the self is shaped by self-perception and social experiences. This distinction highlights the dynamic nature of the...

Area of Science:

  • Social Sciences
  • Statistics
  • Behavioral Science

Background:

  • Studying sensitive behaviors is crucial for effective interventions but challenging due to social desirability bias and fear of retribution.
  • Quantitative Randomized Response Technique (QRRT) estimates the frequency of sensitive behaviors but lacks regression methodology for its count data.
  • Existing methods struggle to identify drivers of non-compliant behavior when using QRRT data.

Purpose of the Study:

  • To develop a novel Poisson regression methodology for analyzing quantitative randomized response technique (QRRT) data.
  • To enable the identification of potential drivers influencing the quantity of sensitive, non-compliant behaviors.
  • To provide a statistical framework for understanding factors contributing to rule-breaking.

Main Methods:

  • Developed a Poisson regression model for QRRT data using maximum likelihood estimation via the expectation-maximization (EM) algorithm.
  • Derived the Fisher information matrix to compute the asymptotic variance-covariance matrix for regression parameter estimates.
  • Validated the methodology through simulations and a case study on hunting regulation non-compliance in Sierra Leone.

Main Results:

  • The new Poisson regression methodology effectively analyzes QRRT data to identify drivers of non-compliant behavior.
  • Simulation results confirmed the accuracy of asymptotic approximations for the regression parameter estimates.
  • The case study successfully illustrated the assessment of potential drivers for varying quantities of non-compliant behavior.

Conclusions:

  • The developed Poisson regression methodology significantly advances the study of sensitive behaviors using QRRT data.
  • This approach allows for a robust assessment of factors influencing non-compliance, offering valuable insights for intervention design.
  • Free, open-source software is available to support the application of QRRT regression, promoting wider research use.
