## (Other) :365###En la tabla anterior podemos encontrar indicadores de estadistica descriptiva,a continuación presentamos datos detallados
MPG:
El consumo de combustible presenta una variabilidad considerable (de 9 a 46.6 mpg), lo que indica la presencia de vehículos tanto muy eficientes como altamente consumidores. Sin embargo, el promedio (23.45 mpg) sugiere una eficiencia moderada en general.
Cilindros:
La mayoría de los vehículos tienen entre 4 y 8 cilindros, siendo 4 el valor más frecuente (mediana = 4). Esto refleja una tendencia hacia autos de menor consumo, aunque también existen vehículos más potentes (hasta 230 hp).
Desplazamiento: Existe una amplia dispersión en el tamaño del motor (68 a 455), lo que confirma la diversidad de tipos de vehículos, desde compactos hasta motores grandes de alto rendimiento.
Peso del vehículo:
El peso varía significativamente (1613 a 5140), lo cual influye directamente en el consumo de combustible: vehículos más pesados tienden a consumir más.
Aceleración:
La aceleración es relativamente homogénea, con una media de 15.54 segundos, indicando que la mayoría de los autos tienen un desempeño similar en este aspecto.
Año de fabricación:
Los datos abarcan vehículos entre 1970 y 1982, con una concentración alrededor de mediados de los años 70, lo que permite analizar tendencias en eficiencia y tecnología de esa época.
a) Creación de la variable binaria mpg01
library(ISLR)
data(Auto)
med_mpg <- median(Auto$mpg)
Auto$mpg01 <- ifelse(Auto$mpg > med_mpg, 1, 0)
table(Auto$mpg01)##
## 0 1
## 196 196Comentario:
Se crea la variable binaria mpg01, donde 1 indica alto rendimiento y 0
bajo rendimiento.
La distribución es balanceada (196 observaciones por grupo).
b) Análisis gráfico
par(mfrow = c(2,3))
boxplot(weight ~ mpg01, data = Auto, main = "Peso")
boxplot(horsepower ~ mpg01, data = Auto, main = "Horsepower")
boxplot(displacement ~ mpg01, data = Auto, main = "Desplazamiento")
boxplot(cylinders ~ mpg01, data = Auto, main = "Cilindros")
boxplot(year ~ mpg01, data = Auto, main = "Año")
boxplot(acceleration ~ mpg01, data = Auto, main = "Aceleración")
par(mfrow = c(1,1))Hallazgos:
- Peso, horsepower y displacement: fuerte relación
con mpg01
- Cylinders: buena capacidad predictiva
- Year: relación moderada
- Acceleration: baja capacidad explicativa
- Peso
Los autos con mpg01 = 1 (alto mpg) tienen mucho menor peso. Las cajas están claramente separadas, con casi nada de superposición.
Conclusión: Es una de las mejores variables para predecir mpg01.
- Caballos de fuerza
Los autos con mayor mpg tienen menor potencia. Diferencia de medianas clara.
Conclusión: También es un predictor muy fuerte.
- Desplazamiento
mpg01 = 1 tiene menores valores de displacement. Las cajas casi no se solapan.
Conclusión: Excelente predictor de mpg01.
- Cilindraje
mpg alto se asocia con menos cilindros. La separación entre grupos es clara, aunque la variable es discreta.
Conclusión: Muy buena variable para clasificar mpg01.
- Año del vehículo
Los autos más recientes tienden a tener mejor mpg. Se observa una diferencia en medianas (aunque no tan fuerte como peso/HP/displacement).
Conclusión: Es útil, pero no tan fuerte como peso o potencia.
- Aceleracion
Diferencias mucho menores. Notable superposición entre boxplots.
Conclusión: Es la variable menos útil para predecir mpg01. —
c) División de datos
set.seed(123)
train <- sample(1:nrow(Auto), 0.7*nrow(Auto))
train_data <- Auto[train, ]
test_data <- Auto[-train, ]Comentario:
Se divide el dataset en 70% entrenamiento y 30% prueba.
d) Modelo LDA
library(MASS)
lda_model <- lda(mpg01 ~ weight + horsepower + displacement + cylinders,
data = train_data)
lda_model## Call:
## lda(mpg01 ~ weight + horsepower + displacement + cylinders, data = train_data)
##
## Prior probabilities of groups:
## 0 1
## 0.4963504 0.5036496
##
## Group means:
## weight horsepower displacement cylinders
## 0 3641.022 130.96324 275.2941 6.786765
## 1 2314.000 78.00725 114.5290 4.188406
##
## Coefficients of linear discriminants:
## LD1
## weight -0.0009670704
## horsepower 0.0049004106
## displacement -0.0029615583
## cylinders -0.3974647924###Los coeficientes nos indican cómo se construye la “frontera” que separa a los dos grupos. El valor de LD1 se calcula como:
\[LD1 = -0.0009 \cdot \text{weight} + 0.0049 \cdot \text{horsepower} - 0.0029 \cdot \text{displacement} - 0.397 \cdot \text{cylinders}\]
Cilindros: Es la variable con el coeficiente más alto en magnitud (-0.397). Esto sugiere que el número de cilindros es un predictor crítico para discriminar entre un auto eficiente y uno que no lo es.Peso y Desplazamiento: Tienen coeficientes negativos, lo que significa que a medida que estos valores aumentan, es más probable que el auto sea clasificado en el grupo de baja eficiencia (Clase 0).

El modelo identificó correctamente a 105 vehículos en total. Falsos Positivos (3): El modelo predijo que 3 autos eran ineficientes cuando en realidad eran eficientes. Falsos Negativos (10): Este es el error más común del modelo; clasificó 10 autos como eficientes cuando en realidad tenían un consumo bajo (mpg01 = 0)

g) Comparación de modelos
resultados <- data.frame(
Modelo = c("LDA", "QDA", "Logística"),
Error = c(error_lda, error_qda, error_glm)
)
resultados## Modelo Error
## 1 LDA 0.1101695
## 2 QDA 0.1016949
## 3 Logística 0.1101695Conclusión general:
Los tres modelos presentan un buen desempeño en la clasificación de
mpg01.
Sin embargo:
- LDA: estable y buen rendimiento general
- QDA: más flexible pero sensible al
sobreajuste
- Regresión logística: equilibrio entre interpretación y precisión
En términos de validación, los modelos no se comportan exactamente igual, siendo LDA y logística los más consistentes.
