Additional information on sample design
and data limitations for specific SOI studies can be found in the separate SOI reports.
In its infancy, the CES program first published estimates without a formal sample design
In the report, "Reduced Incidence of Chikungunya Virus Infection in Communities with Ongoing Aedes Aegypti Mosquito Trap Intervention Studies--Salinas and Guayama, Puerto Rico, November 2015--February 2016," the last sentence of the fifth paragraph should have read, "After adjustment for sample design
, the proportion of chikungunya virus IgG antibody among participants from the two intervention communities was one half that of participants from nonintervention communities (risk ratio = 0-52, 95% confidence interval = 0-38-0-71) (Table)-" The report was first published online as an Early Release on May 10, 2016, and is now contained in this regular May 13 issue
Taking into account practical considerations and using a little finesse during the sample design
and planning stages can ease the implementation and facilitate future use and maintenance of the fixed-asset listing.

The results of the alternative models demonstrate that depending on the variables of interest, authors who fail to incorporate sample design
information or fail to consider the effects of weighting may draw improper inferences from their regression models.
This edition also adds two new chapters on sample design
and implementation, and four methodology appendices on sampling models, organizational surveys, questionnaire evaluation, and cognitive interviewing.
All reported margins of sampling error include the computed design effects for weighting and sample design

Included in the manual are chapters on SASS design, content, and methodology; sample design
and implementation; data collection; response rates; data processing; imputation procedures; weighting and variance estimation; reviewing the quality of SASS data; differences between the restricted-use and public-use data files; sampling, created, weighting, and imputation flag variables; and user notes and cautions.

When an estimate is made using a statistical sample, the estimated value would be expected to be different if a different sample selection was taken from the same population using exactly the same type of sample design
and the same sample size.
