Extend AR(1) log-normal deviances beyond a given year

Replaces the values of an FLQuant beyond a specified year with simulated AR(1) log-normal deviates, using the autocorrelation and standard deviation estimated from the historical period up to and including that year.

Usage

ar1deviances(x, year)

Arguments

x

An FLQuant of log-normal deviances with historical data up to at least year.

year

Integer or character; the last year of the historical period. Values in x after this year will be replaced by simulations.

Value

An FLQuant of the same dimensions as x, with years after year replaced by AR(1) log-normal simulations estimated from the historical data.
