tcsi: return time series with seasonal character randomly

In Nisus-Liu/vava: some frequently-used functions for me

Description

return time series with seasonal character randomly, including TC,S,I.

Usage

tcsi(n, frequency = 12, cyl = 60, intercept = 100, slope = 1,
  s = c(1:12), irr_adj = 0.1)

Arguments

n	number of observation
frequency	monthly: 12; quarter: 4; annual: 1.
cyl	cycle, mean long of cycle.
intercept	intercept of trend line.
slope	slope of trend line.
s	a vector specifing seasonal factor, containing weights for every month.
irr_adj	adjust irregular factor.

Examples

 
plot(tcsi,type = "l")

ts.tcsi<-ts(tcsi,frequency = 12)

plot(decompose(ts.tcsi))
