    Many works of this research group have led to actionable implementations for imputation, estimation, etc. that are mostly available in R.
    For a comprehensive overview of missing values problems and methods in R and in python we refer to our platform R-miss-tastic (established with Nathalie Vialaneix and Nicholas Tierney). Related to this platform is the CRAN Task View on Missing Data maintained by members of this group and Nathalie Vialaneix.
