ridgeSearch: Ridge Regression for Electrode Readings

In EZFragility: Compute Neural Fragility for Ictal iEEG Time Series

Ridge Regression for Electrode Readings

Description

Ridge regression to compute matrix adjancency matrix A such as A xt = xtpt1 the lambda parmeter is found by dichotomy such that A is stable (all eigenvalues have a norm less than one)

Usage

ridgeSearch(xt, xtp1, lambda = NULL)

Arguments

xt	matrix. iEEG time series for a given window, with electrodes names as rows and time points as columns
xtp1	matrix. the iEEG time serie at the next time point, with electrodes names as rows and time points as columns
lambda	Numeric Vector. A user supplied lambda sequence.

Value

adjacency matrix Afin with lambda as attribute
