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...

Regression Analysis

Regression Analysis

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:

Parametric Survival Analysis: Weibull and Exponential Methods

Parametric Survival Analysis: Weibull and Exponential Methods

Parametric survival analysis models survival data by assuming a specific probability distribution for the time until an event occurs. The Weibull and exponential distributions are two of the most commonly used methods in this context, due to their versatility and relatively straightforward application.
Weibull Distribution
The Weibull distribution is a flexible model used in parametric survival analysis. It can handle both increasing and decreasing hazard rates, depending on its shape parameter...

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...

Scatter Plot

Scatter Plot

The most common and easiest way to display the relationship between two variables, x and y, is a scatter plot. A scatter plot shows the direction of a relationship between the variables. A clear direction happens when there is either:

Distributions to Estimate Population Parameter

Distributions to Estimate Population Parameter

The accurate values of population parameters such as population proportion, population mean, and population standard deviation (or variance) are usually unknown. These are fixed values that can only be estimated from the data collected from the samples. The estimates of each of these parameters are sample proportion, the sample mean, and sample standard deviation (or variance). To obtain the values of these sample statistics, data are required that have particular distribution and central...

Biostatistics

Background:

Climate variables are known to influence disease patterns.
Understanding these relationships is crucial for public health in Mexico.
Previous models may not fully capture spatio-temporal variations.

Purpose of the Study:

To investigate the impact of climate variables on the morbidity of specific diseases in Mexico.
To develop and apply a novel spatiotemporal regression model.
To quantify how climate-disease relationships change over space and time.

Main Methods:

Development of a spatiotemporal varying coefficients regression model.
Introduction of a new spatiotemporal-dependent process prior within a Bayesian framework.
Utilizing identically distributed normal marginal distributions and joint multivariate normal distribution.

Main Results:

The influence of climate variables on disease incidence is not uniform across Mexico.
Significant spatio-temporal variations in the effects of climate on disease morbidity were identified.
The proposed model successfully captured and quantified these dynamic changes.

Conclusions:

Climate's impact on disease morbidity in Mexico is complex and varies dynamically.
The developed Bayesian spatiotemporal model provides a robust tool for analyzing these changing relationships.
Findings highlight the need for adaptive public health strategies considering climate variability.
