Market Basket Analysis - Abarrotes

Teoría

El Market Analysis es una técnica en el ámbito de análisis y minería de datos en el campo del comercio. Su objetivo principal es descubrir patrones de asociación entre productos que suelen ser comprados juntos por los clientes.

Las 3 métricas principales para evaluar reglas de asociación son:

• Confidence (confianza): Probabilidad de comprar B sabiendo que se compró A. Ej.Pan –> Mantequilla 0.8 De cada 100 clientes que compraron pan, 80 compraron mantequilla también.
  
• Lift (Elevación): Cuánto más es probable es comprar B cuando se compra A en comparación de la probabilidad de comprar B sin saber si se compró A. Ej. Lift > 1 Compra A impulsa a B. Lift = 1 No tienen relación de compra. Lift > 1 A reduce la compra de B.
  
• Support (Soporte): Popularidad del producto dentro de las transacciones. Ej. Pan y Mantequilla 0.05 El 5% de todas las transacciones compraron estos dos productos juntos.

Contexto

Una cadena de tiendas de convenencia tiene 5 tiendas ubicadas en distintas ciudades de México. La base de datos “abarrotes” contiene 1 mes de transacciones, pero presenta erroes de calidad que impiden realizar análisis confiables. El objetivo es limpiar la base de datos de forma estratégica y posteriormente aplicar MBA para descrubrir patrones de compra y diseñar promociones que aumenten las ventas.

Limpiar la base de datos

Técnica 1. Eliminar valores irrelevantes

#Eliminar columnas
df <- subset(df,select=-c(PLU))

#Eliminar renglones
df <- df[df$Precio>0, ]

Técnica 2. Eliminar valores repetidos

df <- distinct(df)

Técnica 3. Corregir errores tipográficos y similares

df$Unidades <- ceiling(df$Unidades)

Técnica 4. Convertir los tipos de datos

df$Fecha <- as.Date(df$Fecha, format="%d/%m/%Y")

Técnica 5. Tratar valores faltantes

#Borrar todos los NA's
# df <- na.omit(df)

#Reemplazar los NA's con ceros
# df[is.na(df)] <- 0

#Reemplazar los NA's con el PROMEDIO
# df$altura[is.na(df$altura)] <- mean(df$altura, na.rn=TRUE)

Técnica 6. Herraminetas Estadísticas

boxplot(df$Precio, horizontal=TRUE)

boxplot(df$Unidades, horizontal=TRUE)
