SCMid2 function

Scalar Component Model Specification II

Provides detailed analysis of scalar component models for a specified VARMA model. The overall model is specified by SCMid.

SCMid2(zt, maxp = 2, maxq = 2, h = 0, crit = 0.05, sseq = NULL)

Arguments

• zt: The T-by-k data matrix of a k-dimensional time series
• maxp: Maximum AR order specified. Default is 2.
• maxq: Maximum MA order specified. Default is 2.
• h: The additional past lags used in canonical correlation analysis. Default is zero.
• crit: Type-I error used in testing. Default is 0.05.
• sseq: The search sequence for SCM components. Default sequence starts with AR order.

Returns

• Tmatrix: The transformation matrix T

• SCMorder: The orders of SCM components
