Prewhiten stratigraphic series using autoregressive (AR) filter. Appropriate AR order can be automatically determined using the Akaike Information Criterion, or alternatively, the order may be predefined.
prewhiteAR(dat,order=0,method="mle",aic=T,genplot=T,verbose=T)
Stratigraphic series for prewhitening. First column should be location (e.g., depth), second column should be data value for prewhitening. Series must have uniform sampling interval.
AR order for prewhitening (if aic=F), or alternatively, the maximum AR order to investigate (if aic=T). If order is set to <=0, will evaluate up to maximum default order (this varies based on method).
Method for AR parameter estimation: ("yule-walker", "burg", "ols", "mle", "yw")
Select model using AIC? if F, will use order. AIC is only strictly valid if method is "mle".
Generate summary plots? (T or F)
Verbose output? (T or F)
