Member Function Documentation

◆ yoyRate() [1/2]

Rate yoyRate	(	const Date &	d,
		const Period &	instObsLag = `Period(-1,Days)`,
		bool	forceLinearInterpolation = `false`,
		bool	extrapolate = `false`
	)		const

year-on-year inflation rate.

The forceLinearInterpolation parameter is relative to the frequency of the TS.

Note: this is not the year-on-year swap (YYIIS) rate.

◆ yoyRate() [2/2]

Rate yoyRate	(	Time	t,
		bool	extrapolate = `false`
	)		const

year-on-year inflation rate.

Warning:: Since inflation is highly linked to dates (lags, interpolation, months for seasonality, etc) this method cannot account for all effects. If you call it, You'll have to manage lag, seasonality etc. yourself.
