RELAIS (REcord Linkage At IStat)
Toolkit for dealing with record linkage projects.
R package for data integration through statistical matching and, as a by-product, the ability to impute missing values in a data set.
CODING OF TEXTUAL ANSWERS
CIRCE (Comprehensive Istat R Coding Environment)
Automated coding system for textual answers.
DETECTION AND TREATMENT OF MEASUREMENT ERRORS AND IMPUTATION OF PARTIAL NON-RESPONSES
Edit and imputation system for numeric and continuous variables.
CANCEIS (CANadian Census Edit and Imputation System)
Edit and imputation system based on the Nearest-neighbour Imputation Methodology (NIM). The NIM allows the simultaneous hot-deck imputation of numeric and categorical variables based on a single donor. The basic entity that is processed (the unit) can be composed of one or more sub-units of lower hierarchical level.
CONCORDJava (CONtrollo e CORrezione dei Dati version with Java interface)
Integrated system to check and correct the data (imputation). One of the modules (SCIA) implements the Fellegi-Holt Methodology to treat the inconsistencies between the values of qualitative variables.
SeleMix (Selective editing via Mixture models)
R package to treat quantitative data, which aims to identify a set of units affected by errors which potentially influence the interest estimates (selective editing).
WEIGHTING, ESTIMATION AND SAMPLING ERROR EVALUATION
EVER (Estimation of Variance by Efficient Replication)
R package for calibration, estimation and sampling error assessment in complex sample surveys, based on replication methods .
ReGenesees (R evolved Generalised software for sampling estimates and errors in surveys)
R-based software system for design-based and model-assisted analysis of complex sample surveys.
