Muestreo de la encuesta de población finita: una perspectiva bayesiana sin excusas
1University of California Los Angeles, Los Angeles, USA.
Resumen
Este estudio explora la inferencia bayesiana para poblaciones finitas con dependencias complejas. Introduce métodos para manejar las relaciones de unidades y los mecanismos de respuesta, mejorando las capacidades de modelado estadístico.
Área de la Ciencia:
- Las estadísticas
- Inferencia estadística
- Estadísticas computacionales
Sus antecedentes:
- El muestreo de población finita a menudo asume unidades independientes, lo cual es poco realista en muchos escenarios complejos.
- Los modelos jerárquicos bayesianos ofrecen un marco flexible para incorporar información previa y estructuras de datos complejas.
- Los métodos existentes pueden no abordar adecuadamente las dependencias entre las unidades de población.
Objetivo del estudio:
- Proporcionar perspectivas sobre la inferencia bayesiana para cantidades de población finitas con dependencias complejas.
- Extender los marcos inferenciales para acomodar las unidades dependientes y las respuestas no ignorables.
- Para ilustrar las aplicaciones utilizando modelos gráficos y procesos espaciales.
Principales métodos:
- Visión general de los modelos jerárquicos bayesianos, incluidos los que producen estimadores de Horvitz-Thompson.
- Introducción de marcos para mecanismos de respuesta ignorables y no ignorables en poblaciones finitas dependientes.
- Aplicación de dependencias multivariadas utilizando modelos gráficos y procesos espaciales.
Principales resultados:
- Demostración de marcos inferenciales para dependencias complejas en poblaciones finitas.
- Presentación de metodologías para el manejo de respuestas ignorables y no ignorables.
- Análisis ilustrativos de poblaciones espaciales finitas que muestran los métodos discutidos.
Conclusiones:
- La inferencia bayesiana proporciona un enfoque robusto para poblaciones finitas con dependencias complejas.
- Los marcos propuestos mejoran la capacidad de modelar y analizar estructuras de datos dependientes.
- Los modelos gráficos y los procesos espaciales son herramientas valiosas para comprender las dependencias multivariadas.

Distributions to Estimate Population Parameter
4.3K
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...

Sample Proportion and Population Proportion
5.6K
Collecting samples or responses from an entire population takes significant time and effort, so a researcher collects responses from only a sample of that population. Suppose a study needs to collect information about a specific mobile application. After sample collection, the researcher analyzes the data and discovers that most individuals in the sample use that specific mobile application. The sample proportion measures the number of individuals in a sample who either use or don't use the...

Systematic Sampling Method
11.1K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.

Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population.

Cluster Sampling Method

Appropriate sampling methods ensure that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.
To choose a cluster sample, divide the population into clusters (groups) and then randomly select some of the clusters. All the members from these clusters are in the cluster sample. For example, if you randomly sample four departments from your...
