Estimate template from DR

Description

Estimate variance decomposition and templates from DR estimates.

Usage

estimate_template_from_DR(DR, LV = NULL)

Arguments

DR	the test/retest dual regression estimates, as an array with dimensions M \times N \times (L \times V), where M is the number of visits (2), N is the number of subjects, L is the number of IC networks, and V is the number of data locations. (L and V are collapsed because they are treated equivalently in the context of calculating the variance decomposition and templates).
LV	A length-two integer vector giving the dimensions L and V to reshape the result. Default: NULL (do not reshape the result).

Value

List of two elements: the templates and the variance decomposition.

There are two version of the variance template: varUB gives the unbiased variance estimate, and varNN gives the upwardly-biased non-negative variance estimate. Values in varUB will need to be clamped above zero before using in templateICA.
