Description Usage Arguments Details Value Examples

View source: R/ssa.R

Description

This functon constructs an ssa class object to perform a singular spectrum analysis.

Usage

1
ssa(series, window.length = 12)

Arguments

series

a time-series or spatial-series

window.length

the interval length to consider within series

Details

Singular Spectrum Analysis (SSA) is a model-free technique to analyze a 1-D series and extract signal components from noise components. The four basic steps of SSA are: 1. embedding, 2. singular value decomposition, 3. grouping, 4. reconstruction. This constructor function effectively executes steps 1 and 2. The function windowtest serves as a diagnostic aid for parameter selection. The plot, print, summary, and combinepatterns functions aid the user in step 3. Finally, step 4 is accomplished via the reconstruct function.

Value

an object of class ssa
