Description Usage Arguments Details Note Author(s) References
The redfitMinls
function is used by the redfitTauest
function to calculate the persistence for unevenly spaced climate time
series under study. redfitTauest
is included in the
redfit function of the R dplR package (Bunn et al. 2015).
1 | redfitMinls(t, x)
|
t, x |
t and x are the times and the variables for an unevenly spaced time series. |
The redfitMinls
function minimize (optimize) by least
squares to obtain some parameters of the AR1 model used to estimate
the persistence through the method of Mudelsee (2002). More information
about redfitMinls
function can be found in Bunn et al.
(2015) and Mudelsee (2002).
Needs dplR to estimate the persistence contained in the irregular time series by means of the method of Mudelsee (2002). Please, for more details look at the code tauest_dplR.R in the directory R of our BINCOR package.
