Justificación de la variable

La latitud se parametriza como una variable cuantitativa continua esencial para cartografiar la varianza Norte-Sur de los siniestros. Su modelado permite validar si los incidentes se ajustan a una distribución probabilística focalizada, dictada por la densidad de la infraestructura industrial a lo largo de este eje.

1 Cargar Librerias

La estructuración del entorno de programación es el requisito esencial para el análisis. La activación de la librería dplyr permite una manipulación fluida de las coordenadas, mientras que knitr y kableExtra aseguran que las tablas de frecuencias se presenten con la formalidad y el rigor técnico requeridos en el ámbito académico.

2 Cargar datos

Importamos el archivo “database-1.csv” desde una ruta local y lo almacena en el objeto datos, usando comas como separador.

datos <- read.csv("database-_1_.csv", header = TRUE, sep = ",", dec = ".", check.names = FALSE)
names(datos)

3 Extrae la variable

Para este apartado, se aísla la variable referente a la latitud de los incidentes (Accident Latitude). Este parámetro es fundamental para el análisis geoespacial de la red de tuberías. Se procede a una depuración técnica, eliminando valores nulos para asegurar que la muestra sea representativa y esté lista para su posterior agrupación mediante marcas de clase.

zona<-datos$`Accident Latitude`

4 Conteo

Debido a que trabajamos con coordenadas precisas, la tabulación de frecuencias absolutas requiere un enfoque de agrupación. Este conteo inicial permite identificar la dispersión de los registros. (Nota técnica: Para efectos del presente análisis, los resultados obtenidos servirán de base para establecer los rangos de Marca de Clase, permitiendo una representación espacial más adecuada que el uso de grados brutos).

conteo_zona <- table(zona)
print(conteo_zona)

5 Tabla de frecuencia

5.1 Regla de sturges

Extraemos la variable latitud, omitimos las celdas en blanco o valores iguales a cero y verificamos el tamaño muestral. En la tabla de distribución de frecuencias de la variable Latitud del Accidente, el número de clases se determinó mediante la regla de Sturges y el ancho de clase se calculó a partir del rango geoespacial total de los datos, asegurando una cobertura completa desde la coordenada más al Sur hasta la más al Norte.

5.2 Tabla simplificada

Se seleccionó el rango central de la variable Latitud del Accidente para el análisis, omitiendo las coordenadas atípicas (outliers), debido a que en esta zona se concentra la mayor densidad de los datos. Esta elección permite construir la tabla de frecuencia y gráficas más claras y legibles, facilitando la interpretación de la distribución espacial de los siniestros y evitando distorsiones visuales provocadas por ubicaciones extremas (por ejemplo, en latitudes muy altas) con baja frecuencia.

6 Gráficas

6.1 Cantidad de latitud del accidente

Esta visualización macroscópica modela la función de masa espacial en su dominio latitudinal absoluto. El histograma global permite identificar la dispersión total de los eventos y la posible presencia de asimetrías generadas por ubicaciones muy al norte o al sur del clúster principal.

library(ggplot2)
library(dplyr)
library(scales)
datos <- read.csv("database-_1_.csv")
variable_interes <- na.omit(datos$Accident.Latitude)

    y = "Cantidad de Accidentes"
  ) +

    plot.title = element_text(hjust = 0.5, face = "bold"),
    axis.text.x = element_text(angle = 45, hjust = 1)
  )

print(p_global)

6.2 Cantidad de latitud del accidente

Al aislar estadísticamente las colas de la distribución, este apartado evalúa de forma exclusiva el núcleo operativo. Esta amplificación visual revela el comportamiento empírico de la densidad de incidentes en la franja latitudinal de mayor criticidad.

library(ggplot2)
library(dplyr)

    axis.text.x = element_text(hjust = 0.5)
  )

print(p_zoom_5barras)

6.3 Cantidad relativa de latitud del accidente

La transformación estocástica de frecuencias absolutas a proporciones relativas internas permite evaluar la probabilidad de ocurrencia de un evento dentro de los sub-intervalos del núcleo principal, estandarizando la escala de análisis latitudinal.

p_zoom_5barras_pct <- ggplot(datos_zoom, aes(x = Accident.Latitude)) +
  geom_histogram(
    aes(y = after_stat(count / sum(count))), 
    bins = 10,

    axis.text.x = element_text(hjust = 0.5)
  )

print(p_zoom_5barras_pct)

6.4 Cantidad relativa de latitud del accidente

Para dimensionar el peso real de la zona de aglomeración, se contrastan las frecuencias del rango principal contra el universo total de los datos. Esto cuantifica la probabilidad empírica de que un accidente aleatorio pertenezca a este corredor Norte-Sur específico.

p_zoom_5barras_100 <- ggplot(datos_zoom, aes(x = Accident.Latitude)) +
  geom_histogram(
    aes(y = after_stat(count / sum(count))), 
    bins = 10, 
    fill = "steelblue", 
    color = "white", 
    alpha = 0.8
  ) +
  scale_x_continuous(labels = number_format(accuracy = 0.1, suffix = "°")) +
  scale_y_continuous(
    labels = scales::percent_format(accuracy = 1),
    limits = c(0, 1), # Escala de 0 a 100%
    expand = expansion(mult = c(0, 0.05))
  ) +
  
  labs(
    title = "Gráfica No 4: Distribución porcentual global del rango principal",

  )

print(p_zoom_5barras_100)

6.5 Ojivas combinadas

El modelado de la función de distribución acumulada (FDA) bidireccional cartografía la progresión espacial de los incidentes. La intersección de las trayectorias Sur-Norte (ascendente) y Norte-Sur (descendente) señala gráficamente la mediana espacial de la siniestralidad.

library(ggplot2)
library(dplyr)
library(scales)

# Datos locales (del rango principal definido antes)
datos_local <- variable_interes[variable_interes >= limit_min_zoom & variable_interes <= limit_max_zoom]

6.6 Diagrama de cajas

Mediante un enfoque no paramétrico, este diagrama evalúa la dispersión central y el rango intercuartílico (RIC) de las coordenadas latitudinales. Es la herramienta visual óptima para comprobar el grado de apuntamiento y el sesgo direccional de la mediana respecto a la media espacial.

variable_box <- datos_local # Usamos el filtro local
par(mar = c(5, 2, 4, 2)) 
b <- boxplot(variable_box, 
        horizontal = TRUE, 
        col = "skyblue", 
        border = "gray30",

        yaxt = "n",  
        frame = FALSE

7 Tabla estadísticos

Como marco de referencia absoluto, se calculan los estimadores univariantes para la totalidad del vector espacial Norte-Sur. La comparación paramétrica con la tabla local permite medir la distorsión matemática introducida por las latitudes extremas.

library(e1071)
library(knitr)

variable_analisis <- variable_interes # Global
n <- length(variable_analisis)
k_global <- floor(1 + 3.322 * log10(n))
R <- max(variable_analisis) - min(variable_analisis)
A_global <- R / k_global
Li <- seq(min(variable_analisis), max(variable_analisis) - A_global, length.out = k_global)

7.1 Valores Atípicos

Aplicando el criterio analítico de Tukey sobre los cuartiles globales, esta sección identifica las coordenadas espaciales extremas. Estos puntos representan anomalías geográficas severas, es decir, siniestros ubicados a distancias marginales hacia el extremo Norte o Sur.

8 Conclusión

La variable continua Latitud del Accidente fluctúa entre 18.44801° y 70.26126°, con valores que giran en torno a una mediana de 34.93°, presentando una desviación estándar de 5.65° y, a diferencia de las variables de impacto, muestra un comportamiento marcadamente homogéneo (CV del 15.74%). Se identifican apenas 11 valores atípicos (anomalías espaciales) que se ubican a partir de los 63.42546° hacia el extremo norte; asimismo, la distribución exhibe una asimetría positiva (1.06) y una curtosis de 2.97 (prácticamente mesocúrtica o de concentración normal), lo cual indica que la gran mayoría de los siniestros se acumulan en latitudes medias. Este resultado refleja un comportamiento geográfico lógico y esperado, ya que evidencia que el núcleo de los derrames ocurre dentro de la densa red de oleoductos del territorio contiguo de EE. UU., dejando los siniestros en zonas remotas (como Alaska) como eventos espacialmente marginales.
