What is it about?
This paper presents a new statistical model for analyzing data that lie between 0 and 1, such as proportions and percentages. The model is flexible and can represent a wide range of data patterns that commonly occur in real applications. Its usefulness is demonstrated using real data examples, showing improved performance compared to existing methods.

Why is it important?
Data expressed as proportions, percentages, or rates are widely used in many areas of research, including public health, economics, environmental studies, and social sciences. Accurate analysis of this type of data is essential for making reliable conclusions and informed decisions. However, commonly used statistical methods can be too rigid and may fail to reflect important features of real-world data. This work is important because it provides a more flexible and reliable statistical approach for analyzing bounded data. By improving how such data are modeled, the proposed method can lead to more accurate estimates, better interpretation of results, and stronger evidence to support decision-making. As a result, researchers and practitioners can draw clearer conclusions from their data and improve the quality of applied research across many disciplines.
Perspectives
From my perspective, this work was motivated by repeated challenges encountered when analyzing proportion-based data in applied research. In many real situations, existing statistical models do not adequately capture the variability and shape of such data, which can limit meaningful interpretation. Developing a more flexible approach was therefore a natural response to these limitations. I view this contribution as a step toward bridging theoretical development and practical data analysis. My hope is that the proposed method will be accessible to researchers from diverse fields and encourage more careful modeling of bounded data. I also see this work as a foundation for future extensions, including regression modeling and broader applications, which can further enhance its usefulness in real-world studies.
