Inflation_Index__Quote_TypeQuote Type refers to List of inflation rate definitions.
Available Quote Type types:
The index value at any time t is defined as the ratio r(t) = I(t)/b, where:
I(t) is the raw inflation index at time t and
b is the so called "base value", which is a constant that generally represents the value of the raw inflation index at some fixed earlier date.
By "raw inflation index" is here meant the value derived by the available published indices after applying certain interpolation and revision assumptions.
These published indices reference dates that bracket the given date t, but are generally published a few months after t.
The index value at any time t is defined as the annual inflation rate r(t), defined as:
r(t) = I(t)/I(t-1Year) - 1
I(t) is the raw inflation index at time t
