Factorial Design

Factorial Design

Factorial Analysis is an experimental design that applies Analysis of Variance (ANOVA) statistical procedures to examine a change in a dependent variable due to more than one independent variable, also known as factors. Changes in worker productivity can be reasoned, for example, to be influenced by salary and other conditions, such as skill level. One way to test this hypothesis is by categorizing salary into three levels (low, moderate, and high) and skills sets into two levels (entry level...

Residuals and Least-Squares Property

Residuals and Least-Squares Property

The vertical distance between the actual value of y and the estimated value of y. In other words, it measures the vertical distance between the actual data point and the predicted point on the line
If the observed data point lies above the line, the residual is positive, and the line underestimates the actual data value for y. If the observed data point lies below the line, the residual is negative, and the line overestimates the actual data value for y.
The process of fitting the best-fit...

One-Compartment Open Model: Wagner-Nelson and Loo Riegelman Method for k_a Estimation

This lesson introduces two critical methods in pharmacokinetics, the Wagner-Nelson and Loo-Riegelman methods, used for estimating the absorption rate constant (ka) for drugs administered via non-intravenous routes. The Wagner-Nelson method relates ka to the plasma concentration derived from the slope of a semilog percent unabsorbed time plot. However, it is limited to drugs with one-compartment kinetics and can be impacted by factors like gastrointestinal motility or enzymatic degradation.

Multiple Regression

Multiple Regression

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...

Multicompartment Models: Overview

Multicompartment Models: Overview

Multicompartment models are mathematical constructs that depict how drugs are distributed and eliminated within the body. They segment the body into several compartments, symbolizing various physiological or anatomical areas connected through drug transfer processes such as absorption, metabolism, distribution, and elimination.
These models offer a more comprehensive representation of drug behavior in the body than one-compartment models. They accommodate the complexity of drug distribution,...

Background:

Image-on-image regression presents challenges due to high dimensionality and complex spatial dependencies.
Existing methods like linear and voxel-wise regression struggle with these complexities.

Purpose of the Study:

To propose a novel image-on-image regression model addressing high dimensionality and spatial dependence.
To enhance prediction accuracy in multimodal neuroimaging data analysis.

Main Methods:

Extended a spatial Bayesian latent factor model for image data.
Utilized low-dimensional latent factors to connect high-dimensional image predictors and outcomes.
Applied Gaussian process priors to spatially varying regression coefficients.

Main Results:

The proposed method demonstrated superior out-of-sample prediction accuracy compared to linear and voxel-wise regression.
Effectively accounted for spatial dependencies in image data.
Efficiently reduced image dimensions using latent factors.

Conclusions:

The novel spatial Bayesian latent factor model offers improved prediction accuracy for image-on-image regression.
This approach is effective for analyzing complex multimodal neuroimaging datasets like those from the Human Connectome Project.
