I’m curious about how beta coefficient is calculated.
- Below is the beta calculator spreadsheet from an old training material for Bangkok(2015). The first screenshot shows how relative risk is calculated while the second one shows how beta is calculated.
These two formula suggest that relative risk=1+(excess risk/100) and that Beta=In(relative risk/ exposure change),correct?
This is where I got confused. Column E,K and L are values of relative risk( RR). However, the user manual(2015) states that beta is converted from odd ratio. Are we making some assumptions about these two terms while using benMAP?
- I looked at the updated self-paced training materials and it looks like beta values in those seven cities are given to us now. Are they applicable to the whole region or just the given city?
