Estimating Design Effect and Calculating Sample Size for Respondent-Driven Sampling Studies of Injection Drug Users in the United StatesRespondent-driven sampling (RDS) has become increasingly popular for sampling hidden populations, including injecting drug users (IDU). However, RDS data are unique and...

MultSampSizeDescriptionMultSampSize is a Shiny app which can be used to calculate the sample size required for studies using a latent variable to analyse mixed outcome endpoints in the form of:Co-primary - requires an effect in all outcomes Multiple primary - requires an effect in at least ...
This paper proposes a methodology to estimate the required sample size to assess, with a specified precision, the localized corrosion of process components. The proposed methodology uses the extreme value and bootstrap methods. The results of estimated sample size ensure that the predicted maximum loc...
