Familywise Error Familywise error (FWE) is also known as alpha inflation or cumulative Type I error. Familywise error represents the probability that any one of a set of comparisons or significance tests is a Type I error. As more tests are conducted, the likelihood that one or more are significant just due to chance (Type I error) increases. One can estimate familywise error with the following...

I am surprised by the published conclusions of Hung et al 1 in a recent issue of CHEST (August 2013). The authors’ stated meth ods are not adequate to support their conclusion that hyperimmune IV immunoglobulin (H-IVIG) ben efi ts mortality if given within 5 days to patients with severe 2009 infl uenza A(H1N1) infection. The primary outcome analysis of 34 patients presented in Table 1 of the st...

Body mass indices (BMIs) are applied to monitor weight status and associated health risks in populations.  Binary or multinomial logistic regression models are commonly applied in this context, but are only applicable to BMI values categorized within a small set of defined ad hoc BMI categories.  This approach precludes comparisons with studies and models based on different categories.  In addi...
