In neuroconductor-devel/pbj: Parametric Bootstrap Joint Testing Procedures for Neuroimaging

Description

Constructs (semi)Parametric Bootstrap Joint ((s)PBJ) Coverage Probability Excursion (CoPE) Sets

Usage

pbjExSet(statMap, ses = 0.2, nboot = 5000, boundary = FALSE,
  eps = 0.01)

Arguments

statMap	statMap object as obtained from computeStats.
ses	minimum effect size of interest for.
nboot	Number of bootstraps to perform.
boundary	Sample from the boundary as in Sommerfeld et al. (2018).
eps	tolerance for the chi-square statistic. Only used if boundary is TRUE and the degrees of freedom is 1.

Value

Returns a list of length length(ses)+2. The first two elements contain statMap$stat and statMap$template. The remaining elements are lists containing the following:

Aminus	Aminus<=1-alpha contains EstatMap$stat>chsq with probability 1-alpha.
Aplus	Aplus>1-alpha is contained in EstatMap$stat>chsq with probability 1-alpha.
ses	A minimum threshold to define interesting locations. It is the proportion of signal in the chi-square statistic.
chsq	ses converted to the chi-squared scale using chsq = ( (n-1) \* ses + 1) /(1-ses) \* df.
CDFs	The bootstrap CDFs used to compute Aminus and Aplus.
