Find out what the MII is, how it’s different from the MIIplus, and what both can (and can’t) tell us about the quality of reproductive health counseling. Executive Summary: The MII and MIIplus are sets of “yes or no” questions. WebbVad är en indexfond? En indexfond är en typ av aktiefond som följer ett visst index. Fonden kan till exempel följa ett index som heter OMX Stockholm 30, som återspeglar avkastningen från de 30 mest handlade aktierna på Stockholmsbörsen. Då består den indexfonden av just dessa 30 bolag.

WebbShannon or Shannon--Weaver (or Shannon--Wiener) index is defined as H ′ = − ∑ i p i log b p i, where p i is the proportional abundance of species i and b is the base of the logarithm. It is most popular to use natural logarithms, but some argue for base b = 2 (which makes sense, but no real difference). http://web.mit.edu/6.933/www/Fall2001/Shannon2.pdf
