Missing data: un ejemplo práctico

The absolute risk of dying from snakebite by the age of 70, across India. Snakebite deaths are highly spatially concentrated. About 0.33% of the population lived in areas with a risk ≥1%, while 21% of the population lived in areas with a risk ≥0.6%. Source: Wilson Suraweera et al. (2020).

Missing data: un ejemplo práctico

Missing data: consecuencias

  • Sesgo, salvo que sea completamente aleatorio (a continuación)
  • Pérdida de potencia: menos n efectivo si eliminas filas
  • Varianzas sub/overestimadas: puede afectar inferencia (se, ic),
  • Predicción: modelos pueden degradarse si la generación de NA difiere entre entrenamiento y despliegue

¿Por qué faltan datos y qué implica?

  • Missing completely at random (MCAR): faltan al azar puro (probabilidad de NA no depende de nada).
  • Missing at random (MAR): faltan condicionalmente a variables observadas (supuesto típico de MICE).
  • Missing not at random (MNAR): faltan dependiendo del propio valor ausente (más difícil; requiere supuestos/modelado).

Missing completely at random (MCAR)

La ausencia es independiente de datos observados y no observados ⇒ insesgadez

Banner

Missing completely at random (MCAR)

Por ejemplo, falló el sensor en un 10% de mediciones por cortes de luz aleatorios.

MAR (Missing At Random)

La ausencia puede depender de \(X\) observado

Banner

MAR (Missing At Random)

La ausencia puede depender de \(X\) observado

Banner

MAR (Missing At Random)

Por ejemplo, probabilidad de no responder ingreso depende de educación y edad (observados).

MNAR (Missing Not At Random)

La ausencia depende de \(Y\) aún condicionando a \(X\)

Banner

MNAR (Missing Not At Random)

Por ejemplo:

  • Probabilidad de no responder ingreso depende del ingreso mismo, incluso controlando por educación/edad.
  • Participantes con niveles muy altos de estrés podrían elegir conscientemente no revelar su nivel de estrés debido al estigma o al miedo al juicio.

MCAR vs. MAR vs. MNAR

  • Antes de imputar, modela el mecanismo de ausencia
  • MAR es un supuesto, no un hecho; más plausible añadiendo indicios
  • Ignorar el mecanismo casi siempre sale caro: sesgo o falsa precisión
  • Reporta sensibilidad: resultados “con y sin”, y distintos supuestos con sospecha de MNAR

Antes de imputar

1. Decidir si eliminar filas (row-wise)

  • %NA por fila es bajo
  • NA parecen MCAR
  • Perder n no cambia el poder estadístico

Ojo: Usar solo casos completos sesga, salvo MCAR

2. Decidir si eliminar variables (column-wise)

  • Muy alta tasa de NA
  • Baja relevancia predictiva
  • Es redundante o reemplazable por otra bien observada

3. Imputación simple

  • Media/mediana/moda/constante, KNN, regresión, etc
  • Rápido pero subestima la incertidumbre.

4. Imputación múltiple

  • Varias imputaciones, análisis por imputación y pooling con Reglas de Rubin
  • Refleja incertidumbre

5. Modelos robustos a NA

  • Algunos algoritmos (p. ej., xgboost, lightgbm) manejan NA internamente (ojo con leakage al comparar)
  • Ojo para ML: evitar leakage. Es decir, imputa dentro del train (o dentro de cada fold de CV), no con todo el dataset.
