Seleccion de variables

Documento generado para la seleccion de variables en el modelo de regresion lineal multiple. En este caso, se utilizara la base de datos de WordClimate para la seleccion de variables. Se utilizara el paquete raster para leer los datos raster y el paquete dplyr para manipular los datos. Se utilizara el paquete ggplot2 para graficar los resultados.

Conclusiones

En este análisis, hemos realizado una selección de variables para un modelo de regresión lineal múltiple utilizando datos climáticos de WordClimate. Los pasos clave incluyen:

1. Lectura y preparación de datos: Cargamos los datos raster y aseguramos que todos tengan la misma extensión y resolución. También imputamos valores faltantes mediante muestreo aleatorio.

2. Análisis exploratorio: Evaluamos la presencia de valores faltantes y graficamos los primeros cuatro mapas para visualizar las variables.

3. Selección de covariables: Calculamos la matriz de correlación y visualizamos las relaciones entre las variables. Identificamos pares de variables altamente correlacionadas y eliminamos aquellas con un VIF mayor a 10 para evitar multicolinealidad.

4. Resultados finales: Creamos un nuevo data.frame con las variables seleccionadas y guardamos tanto el data.frame como el objeto raster resultante.

Recomendaciones

Para futuros análisis, se recomienda: - Realizar un análisis más profundo de las variables seleccionadas para entender su impacto en el modelo. - Considerar la inclusión de técnicas de reducción de dimensionalidad, como PCA, si se trabaja con un gran número de variables. - Evaluar el modelo de regresión lineal múltiple con las variables seleccionadas para validar su rendimiento y ajustar según sea necesario.
