The SF36rec
function recodes the Short Form36 Health Survey (SF36) dimensions into binomial data, based on Arostegui et al. (2013).
1  SF36rec(x,k)

x 
The SF36 dimension to be recoded, it must be numeric and bounded between 0 and 100. 
k 
An integer from 1 to 8, indicating the SF36 dimension of

Each observation of the HRQoL measured by the SF36 is divided in eight domains, and each domain refers to an especific aspect of the HRQoL: Role Physical, Role Emotional, Physical Functioning, Vitality, Social Functioning, Body Pain, General Health and Mental Health. This domains are bounded between 0 and 100, and each domain can only take some values. This function recodes the SF36 domains based on the method proposed in Arostegui et al. (2013) for the betabinomial regression analysis.
The dimension recoded to binomial data.
