Does Repeated Measurement Improve Income Data Quality?

Trend-resistant repeated measurement Designs

 The existence and non-existence of trend-resistant repeated measurement designs are investigated. Two families of efficient/optimal repeated measurement designs which are very popular among experimenters are shown to be trend-resistant or trend-resistant with respect to treatments.

Does data splitting improve prediction?

Data splitting divides data into two parts. One part is reserved for model selection. In some applications, the second part is used for model validation but we use this part for estimating the parameters of the chosen model. We focus on the problem of constructing reliable predictive distributions for future observed values. We judge the predictive performance using log scoring. We compare the ...

Does Mentioning ‘‘some People’’ and ‘‘other People’’ in an Opinion Question Improve Measurement Quality?

Researchers often measure attitudes and beliefs using ‘‘some/ other’’ questions (‘‘Some people think that . . . but other people think that . . .’’) instead of asking simpler ‘‘direct’’ questions. This article reports studies testing the hypothesis that the some/other question form yields improved response validity. Eight experiments embedded in national surveys provided no evidence in support ...
