  • D- and MS-optimal 2-Level Choice Designs for $N\not\equiv 0$ (mod 4) 
    Singh, Rakhi; Chai, Feng-Shun; Das, Ashish (2014-11-22)
    Street and Burgess (2007) present a comprehensive exposition of designs for choice experiments till then. Our focus is on choice experiments with two-level factors and a main effects model. We consider designs for choice ...
  • On optimal two-level supersaturated designs 
    Singh, Rakhi; Das, Ashish (2015-02-04)
    A popular measure to assess two-level supersaturated designs is the $E(s^2)$ criteria. Recently, Jones and Majumdar (2014) introduced the $\mbox{{\it UE}}(s^2)$ criteria and obtained optimal designs under the criteria. ...
  • Optimal Paired Choice Block Designs 
    Singh, Rakhi; Das, Ashish; Chai, Feng-Shun (2015-09-16)
    Choice experiments mirror real world situations closely and helps manufacturers, policy-makers and other researchers in taking business decisions on their product characteristics based on its perceived utility. In a paired ...
  • Optimal two-level choice designs for estimating main effects and specified two-factor interactions 
    Chai, Feng-Shun; Das, Ashish; Singh, Rakhi (2015-10-11)
    Over two decades, optimal choice designs have been obtained for estimating the main effects and the main plus two-factor interaction effects under both the multinomial logit model and the linear paired comparison model. ...
  • Three-level A- and D-optimal paired choice designs 
    Chai, Feng-Shun; Das, Ashish; Singh, Rakhi (2016-02-29)
    In a paired choice experiment, several pairs of options are shown to respondents and the respondents are asked to give their preference among the two options for each of the choice pairs shown to them. Under the utility ...
  • A unified approach to choice experiments 
    Das, Ashish; Singh, Rakhi (2016-04-29)
    Choice experiments have practical significance from the industry point of view and are useful in marketing, transport, government planning, etc. Several author-groups have contributed to the theoretical development of ...
