1 Configuración y Carga de Datos
Se carga el conjunto de datos de arrendamientos de hidrocarburos del estado de Kansas, EE.UU., registrados por el Kansas Geological Survey, para proceder con el análisis inferencial de la variable cualitativa nominal Nombre del Operador.
ruta_archivo <- "C:/Users/thann/OneDrive/Escritorio/ESTADISTICA.LOL/datos_vale.csv"
if (file.exists(ruta_archivo)) {
datos <- read_delim(ruta_archivo, delim = ";", show_col_types = FALSE)
} else {

La variable OPERATOR_NAME corresponde a Nombre del Operador. Se eliminan los registros sin valor; si la variable es dicotómica, se conservan únicamente los valores válidos indicados. En las variables nominales policotómicas con muchas categorÃas, las tablas y gráficas descriptivas se presentan con las categorÃas más frecuentes, conservando el total de observaciones válidas para el cálculo de \(h_i\).
if (length(valores_validos) > 0) {
x_raw <- datos %>%
filter(.data[[variable_tecnica]] %in% valores_validos) %>%
pull(.data[[variable_tecnica]])
} else {
x_raw <- datos %>%
filter(!is.na(.data[[variable_tecnica]]), .data[[variable_tecnica]] != "") %>%
pull(.data[[variable_tecnica]])
}
if (traduccion_si_no) {

)
}

Justificación: La variable es cualitativa nominal porque sus categorÃas no poseen orden natural. En variables nominales, la probabilidad de ocurrencia de cada categorÃa se estima mediante su frecuencia relativa observada:
\[P(X = x_i) = h_i = \frac{n_i}{n}\]
donde \(n_i\) es la frecuencia absoluta de la categorÃa \(i\) y \(n\) es el total de observaciones válidas.

6 Identificación del Modelo ProbabilÃstico Inferencial
La variable Nombre del Operador es cualitativa nominal. Para una variable nominal, las categorÃas no tienen jerarquÃa ni distancia numérica; por ello, la probabilidad de ocurrencia de cada valor se estima directamente con la frecuencia relativa observada:
\[P(X = x_i) = h_i\]
El comportamiento probabilÃstico puede representarse mediante un modelo categórico:
\[X \sim \text{Categórica}(\pi_1, \pi_2, \ldots, \pi_k)\]
donde:
\[\pi_i = P(X = x_i) = h_i = \frac{n_i}{n}\]
Por tanto, para este análisis inferencial no se asigna una probabilidad por orden o jerarquÃa, sino por la proporción observada de cada categorÃa.
tabla_frec <- data.frame(
Categoria = categorias,
Observada = ni,
stringsAsFactors = FALSE
) %>%
mutate(
h_i = Observada / n,
Probabilidad_Nominal = h_i,
Porcentaje = h_i * 100
)
k <- nrow(tabla_frec)
moda_val <- names(freq_abs)[1]
moda_n <- as.integer(freq_abs[1])
moda_hi <- moda_n / n

8 Intervalos de Confianza por CategorÃa
Se estima el intervalo de confianza al 95% para la proporción poblacional de cada categorÃa. El estimador puntual de cada probabilidad nominal es:
\[\hat{p}_i = h_i\]
y el intervalo de confianza se calcula mediante:
\[IC_{95\%}: \hat{p}_i \pm z_{\alpha/2}\sqrt{\frac{\hat{p}_i(1-\hat{p}_i)}{n}}\]

9 Test de Pearson para el Modelo Nominal
Como la variable Nombre del Operador es nominal, no se fuerza una probabilidad teórica uniforme para sus categorÃas. En su lugar, el modelo probabilÃstico nominal se construye con las probabilidades observadas:
\[P(X = x_i) = h_i\]
Por tanto, el Test de Pearson compara las frecuencias observadas con las frecuencias esperadas del propio modelo nominal:
\[E_i = n \cdot h_i\]
De esta forma, se evalúa el ajuste entre los datos observados y el modelo nominal estimado a partir de las frecuencias relativas.
9.1 Planteamiento de Hipótesis
\[H_0: \text{La variable se ajusta al modelo nominal } P(X = x_i) = h_i\]
\[H_1: \text{La variable no se ajusta al modelo nominal } P(X = x_i) = h_i\]
Nivel de significancia: \(\alpha = 0.05\)
9.2 EstadÃstico de Pearson
El estadÃstico de Pearson se calcula como:
\[X_P^2 = \sum_{i=1}^{k}\frac{(O_i - E_i)^2}{E_i}\]
tabla_pearson <- tabla_frec %>%
mutate(
Esperada_Pearson = n * h_i,
Diferencia = Observada - Esperada_Pearson,
Componente_Pearson = ifelse(Esperada_Pearson > 0, (Diferencia^2) / Esperada_Pearson, 0)
)
pearson_estadistico <- sum(tabla_pearson$Componente_Pearson)
pearson_ajuste <- 100 / (1 + pearson_estadistico)
pearson_resultado <- ifelse(pearson_ajuste >= 95, "Modelo aceptado", "Modelo no aceptado")

12 Conclusiones
La variable Nombre del Operador fue analizada como una variable cualitativa nominal policotã³mica, porque sus categorÃas no poseen orden natural. Por esta razón, la probabilidad de ocurrencia de cada valor se estimó mediante su frecuencia relativa observada, es decir, \(P(X = x_i) = h_i\).
La categorÃa modal fue “Scout Energy Management LLC”, con una probabilidad nominal estimada de \(h_i = 0.0627\). Los intervalos de confianza al 95% permiten estimar el rango plausible de la proporción poblacional de cada categorÃa. Además, el Test de Pearson para el modelo nominal obtuvo un estadÃstico de 0 y un ajuste de 100%, por lo que el resultado inferencial fue: Modelo aceptado.
En sÃntesis, el análisis inferencial conserva la naturaleza nominal de la variable y expresa sus probabilidades mediante \(h_i\), complementando las tablas y gráficas descriptivas con intervalos de confianza y Test de Pearson.
