A correlated chisquare minimisation is performed on the original data as
well as on all bootstrap samples generated by
bootstrap.effectivemass
. The inverse covariance matrix is generated
as described in heplat/9412087 in case of too little data to relibably
estimate it.
An object with class effectivemassfit
is returned. It
contains all the data of the input object effMass
with the following
additional member objects:
opt.res
: the object returned by the optim
on the original
data.
massfit.tsboot
: the bootstrap values of the mass and the chisquare
function.
ii
: the index array of data used in the fit.
invCovMatrix
: the inverse covariance matrix.
dof
: the degrees of freedom of the fit.
t1,t2
: the fit range.
