End-of-Period Series, Stats, and Benchmarks

Computes perodical statistics back to a given period.

Keywords: chron

Usage

endOfPeriodSeries(x,  nYearsBack = c("1y", "2y", "3y", "5y", "10y", "YTD"))
endOfPeriodStats(x,  nYearsBack = c("1y", "2y", "3y", "5y", "10y", "YTD")) 
endOfPeriodBenchmarks(x, benchmark = ncol(x), nYearsBack = c("1y", "2y", "3y", "5y", "10y", "YTD"))

Arguments

x: an end-of-month recorded multivariate 'timeSeries' object. One of the columns holds the benchmark series specified by the argument benchmark, By defauklt this is the last column of x.
nYearsBack: a period string. How long back should the series be treated? Options include values from 1 year to 10 years, and year-to-date: "1y", "2y", "3y", "5y", "10y", "YTD".
benchmark: an integer giving the position of the benchmar series in x.

Details

The function endOfPeriodSeries returns series back to a given period. The function endOfPeriodStats returns statistics back to a given period. The function endOfPeriodBenchmarks returns benchmarks back to a given period. x must be end of month data. Note you can create such series using for example the functions: align, alignDailySeries, daily2monthly.

Examples

library(timeSeries)

## Load Series: Column 1:3 Swiss Market, Column 8 (4) Benchmark
   x <- 100 * LPP2005REC[, c(1:3, 8)]
   colnames(x)
   x <- daily2monthly(x)
   x
   
## Get the Monthly Series - 
   endOfPeriodSeries(x, nYearsBack="1y")
   
## Compute the Monthly Statistics - 
   endOfPeriodStats(x, nYearsBack="1y")
   
## Compute the Benchmark - 
   endOfPeriodBenchmarks(x, benchmark=4)
