mftsc {ftsa} | R Documentation |
Multiple funtional time series clustering
Description
Clustering the multiple functional time series. The function uses the functional panel data model to cluster different time series into subgroups
Usage
mftsc(X, alpha)
Arguments
X |
A list of sets of smoothed functional time series to be clustered, for each object, it is a p x q matrix, where p is the sample size and q is the number of grid points of the function |
alpha |
A value input for adjusted rand index to measure similarity of the memberships with last iteration, can be any value big than 0.9 |
Details
As an initial step, conventional k-means clustering is performed on the dynamic FPC scores, then an iterative membership updating process is applied by fitting the MFPCA model.
Value
iteration |
the number of iterations until convergence |
memebership |
a list of all the membership matrices at each iteration |
member.final |
the final membership |
