Response Surface Methodology01:16

Response Surface Methodology

595
Response Surface Methodology (RSM) is a collection of statistical and mathematical techniques used to develop, improve, and optimize processes. It is particularly valuable when many input variables or factors potentially influence a response variable.
The process of RSM involves several key steps:

Randomized Experiments

The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

Multiple Regression01:25

Multiple Regression

3.7K
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...

Friedman Two-way Analysis of Variance by Ranks01:21

Friedman Two-way Analysis of Variance by Ranks

477
Friedman's Two-Way Analysis of Variance by Ranks is a nonparametric test designed to identify differences across multiple test attempts when traditional assumptions of normality and equal variances do not apply. Unlike conventional ANOVA, which requires normally distributed data with equal variances, Friedman's test is ideal for ordinal or non-normally distributed data, making it particularly useful for analyzing dependent samples, such as matched subjects over time or repeated measures...

Mechanistic Models: Compartment Models in Individual and Population Analysis

237
Mechanistic models are utilized in individual analysis using single-source data, but imperfections arise due to data collection errors, preventing perfect prediction of observed data. The mathematical equation involves known values (Xi), observed concentrations (Ci), measurement errors (εi), model parameters (ϕj), and the related function (ƒi) for i number of values. Different least-squares metrics quantify differences between predicted and observed values. The ordinary least...

Random Variables01:09

Random Variables

17.3K
A random variable is a single numerical value that indicates the outcome of a procedure. The concept of random variables is fundamental to the probability theory and was introduced by a Russian mathematician, Pafnuty Chebyshev, in the mid-nineteenth century.
Uppercase letters such as X or Y denote a random variable. Lowercase letters like x or y denote the value of a random variable. If X is a random variable, then X is written in words, and x is given as a number.
For example, let X = the...

Area of Science:

  • Social Sciences
  • Biostatistics
  • Health Services Research

Background:

  • Surveys in social sciences frequently involve sensitive questions.
  • Indirect questioning methods, such as the randomized response technique, protect respondent privacy while gathering essential data.
  • The randomized response technique uses randomization to collect sensitive responses securely.

Purpose of the Study:

  • To propose a multivariate ordered probit model for joint analysis of binary and ordinal sensitive data.
  • To develop Bayesian methods for estimating the probit model and performing posterior inference.
  • To apply the model to a drug administration survey in Hong Kong hospitals.

Main Methods:

  • Development of a multivariate ordered probit model.
  • Application of Bayesian inference techniques for model estimation.
  • Utilizing the randomized response technique in a large-scale hospital survey.

Main Results:

  • The proposed probit model successfully analyzes sensitive binary and ordinal data.
  • Empirical results from the drug administration survey provide insights into staff medication practices.
  • The model identifies potential deviations from official hospital guidelines.

Conclusions:

  • The developed statistical model enhances the analysis of sensitive survey data.
  • Understanding staff medication practices is crucial for improving drug administration procedures.
  • This approach aids in identifying areas for staff training and procedural enhancement in healthcare settings.
