This results in the creation of a residual series that is referred to as the detrended series. ❋ Unknown (2006)
This is doubtless why MBH98 used something called detrended standard deviations, which do not downweight hockey stick shaped series. ❋ Unknown (2005)
His feat of finding no trend in detrended munged data is on a par with John Ashcroft's triumph in finding 12 hookers in New Orleans. ❋ EliRabett (2010)
Our analysis shows that properly detrended, integrated solar are index is well described as an uncorrelated Lévy flight, while the detrended, integrated temperature anomaly record is consistent with a persistent fractional Brownian motion. ❋ EliRabett (2009)
So the plot above is the “detrended” sequence length. ❋ Unknown (2007)
For the GTA, it turns out that if the time series is properly detrended the Hurst parameter 0.65 indicates that the steps are positively correlated, e.g changes in global temperature anomalies on a monthly basis are correlated at least a few steps out from any point and the series can be described as a fractional Brownian process. ❋ EliRabett (2009)
They show that the test used by S&W on series with a long term trend will make them all appear similar, and that if the GTA and SFI are detrended the correlation disappears. ❋ EliRabett (2009)
R2 argue that any idiot can tell the difference between the step size distribution in the SFI and GTA by removing the long time trends and then looking at the detrended probability distribution functions. ❋ EliRabett (2009)
I calculated chi square goodness of fit probabilities for the raw named storm time series and then again for the series detrended and with the cyclical component removed. ❋ Unknown (2007)
I should have reminded you all of the post where Willis E showed graphically the dramatically improved fit with a Poisson distribution for a detrended NATL hurricane time series and the cyclical component removed. ❋ Unknown (2007)
This is reflected in the significance scores Table 3 which are high both for the full series and for the detrended series. ❋ Unknown (2007)
A periodicity analysis of the detrended cyclone data indicates a strong peak at about 60 years. ❋ Unknown (2007)
Since the tropical storm count series the category Total storms when detrended and with the cyclical component removed by Willis E showed an excellent fit to a Poisson distribution, I would conjecture that the Easy Detection category storms would need to have the cyclical component removed to better fit a Poisson distribution. ❋ Unknown (2007)
If you detrended world temperature data of the global warming trend, I imagine you would get a similar graph to that you see for the PDO, as global warming has not been perfectly linear, rather it oscillates around the linear trend ie positive ~1915-1945, negative ~1945-1978, positive ~1970-2000ish. ❋ Unknown (2007)
I understand it relates to the poleward of 20N SST anomaly, and is detrended of the Global Warming trend. ❋ Unknown (2007)
It would have been interesting if they had taken two additional steps: (1) use detrended SST in their analysis and (2) use SST contrast (MDR SST vs tropical South Atlantic SST). ❋ Unknown (2007)
