Selection of balanced portfolios to track the main properties of a large market
Donatien Tafin Djoko,Yves Tillé +1 more
TL;DR: In this paper, a survey sampling framework is used to construct a small portfolio to track the total market capitalization (TMC) of the S&P500 constituents of the stock market, and the portfolio is randomly selected using a new method of balanced sampling.
Journal ArticleDOI
Computational aspects of order πps sampling schemes
Alina Matei,Yves Tillé +1 more
TL;DR: In this paper, a simple method to compute @p"k from @l"k is presented, and it is used to compute the inclusion probabilities of order @pps sampling schemes (uniform, exponential and Pareto).
Journal ArticleDOI
A variant of the Cox algorithm for the imputation of non-response of qualitative data
TL;DR: A modification of the Cox algorithm is proposed in order to take into account a weighting system, which is commonly used in survey sampling, and allows to construct a controlled imputation method that reduces the imputation variance.

Balanced k-Nearest Neighbor Imputation
Caren Hasler,Yves Tillé +1 more
TL;DR: In this paper, the authors presented a new random hot-deck imputation method which enables selecting the imputed values such that some balancing equations are satised and such that the donors are selected in neighborhoods of the recipients.
Journal ArticleDOI
Sampling Procedures for Coordinating Stratified Samples: Methods Based on Microstrata
TL;DR: Six new methods based on permanent random numbers (PRNs) and microstrata have the advantage of allowing us to choose between positive or negative coordination with each of the previous samples, and are presented.
