    Aggregate precision of a measurement instrument based on a sample of measurements whose true errors are known

    I want to estimate the accuracy and precision of aggregate data from an instrument that measures a variable that fluctuates over time by comparing a sample of its measurements to concurrent measurements made by a reference instrument. For this purpose, assume that the reference instrument...

    Household surveys: Estimating precision for indices built at individuals level

    I am using survey data that contains information of households and of individuals (household members). The sample size was determined at household level, and the sample was selected using a stratified cluster design. I have created a simple additive scale using several dummy variables, some...
