Goal Linear Programming Method To Determine Multiple Regression

Feb 27, 2025 by ADMIN 64 views

Introduction

In the field of statistics, linear regression is a widely used technique to model the relationship between a dependent variable and one or more independent variables. However, when dealing with multiple independent variables, the traditional linear regression method may not be sufficient to capture the complex relationships between the variables. This is where the Goal Linear Programming method comes into play. In this article, we will discuss the application of the Goal Linear Programming method to determine multiple regression coefficients.

Understanding Linear Regression

Simple linear regression is a statistical technique used to show the relationship between two variables. In this context, variable X acts as an independent variable, while the Y variable is the dependent variable. The general formula for simple linear regression can be stated as follows:

${ Y = β_0 + β_1 x + e }$

Where:

${ Y }$ is a dependent variable.
${ x_i }$ is an independent variable.
${ β_0 }$ is an intercept (the intersection point of the curve with the y-axis).
${ β_1 }$ is a slope.
${ E }$ is an error.

From the available data, we can calculate the following error values:

${ \Lambda = y - \hat{y} }$

where ${ \hat{y} }$ is a predicted value.

Application of Linear Programming Goal

The Goal Linear Programming method is the right approach in determining the multiple regression coefficient. In this context, we can use this method to optimize the estimated dependent variable based on the available independent variables. The use of goal-linear programming provides benefits because it allows us to minimize estimation errors by considering various boundaries that may be present in the dataset.

The Advantages of This Method

Efficiency in Calculation: This method is able to handle large amounts of data simultaneously, so that the process of searching the regression coefficient becomes more efficient.
Handling Limits: In many cases, there are limits that must be considered when doing regression, such as limits on independent variables. Linear programming allows us to enter these boundaries in the model.
More Accurate Results: By minimizing estimation errors, the results obtained from this method tend to be more accurate than traditional regression methods.

Steps in Applying This Method

Identification of Variables: Determine the independent and dependent variables you want to study.
Collect Data: Collect relevant data for regression analysis.
Determine the Model: Build a linear regression model using the equation mentioned above.
Apply Goal Linear Programming: Use the goal-linear programming method to optimize the estimated dependent variable based on the available independent variables.
Evaluate the Results: Evaluate the results obtained from the goal-linear programming method and compare them with the traditional regression method.

Case Study

Let's consider a case study to illustrate the application of the Goal Linear Programming method in determining multiple regression coefficients. Suppose we want to model the relationship between the price of a house and its characteristics, such as the number of bedrooms, the size of the house, and the location. We collect data on these variables and want to determine the multiple regression coefficients using the goal-linear programming method.

Conclusion

The goal linear programming method is a very useful approach in determining the multiple regression coefficient. With its ability to minimize errors and accommodate various boundaries, this method is the right choice in regression analysis. With a good understanding of linear regression and application of this method, researchers can obtain more accurate and informative results.

While the goal linear programming method has several advantages, it also has some limitations. Some of these limitations include:

Computational complexity: The goal-linear programming method can be computationally complex, especially when dealing with large datasets.
Assumptions of the method: The goal-linear programming method assumes that the relationship between the variables is linear, which may not always be the case.
