HERE»S WHAT I DO N'T LIKE: Loud wind noise (anytime I exceed 40 - 45 mph), makes it hard to hear the radio at normal volume; intrusive road noise, which I corrected by swapping out the standard Goodyear tires with Continental tires; lackluster acceleration for a V6 engine, CVT tends to lose momentum when you lift your foot off of the gas pedal — often jerky when accelerating and decelerating while in motion and when accelerating from a dead stop; as mentioned by another reviewer, accelerator hesitates before catching when shifting from reverse to drive; bumps in the road are not well absorbed (the 2016 model may have addressed this issue); no power to windows after you shut off the engine; no auto door locks; poor V6 fuel efficiency averaging around 24 MPGs combined; trunk lid's arms and safety feature makes it heavy and sometimes hard to lift open; Infotainment system does understand most voice commands; and Harmon Kardon speakers are sometimes crackly.

Simon # 339, the past trends, the averages, the weighting of the data, better delineation of noise versus signal and using the laws of physics as a foundation while at least modeling clouds is a big step in the right direction.

Despite being beloved of statistical modellers everywhere, ARMA is actually a pretty crude model — it's just a linear autoregressive chain combined with weighted moving average white noise.

In the case of climate models, this is complicated by the fact that the time scales involved need to be long enough to average out the short - term noise, i.e. the chaotic sequences of «weather» events.

In a system such as the climate, we can never include enough variables to describe the actual system on all relevant length scales (e.g. the butterfly effect — MICROSCOPIC perturbations grow exponentially in time to drive the system to completely different states over macroscopic time) so the best that we can often do is model it as a complex nonlinear set of ordinary differential equations with stochastic noise terms — a generalized Langevin equation or generalized Master equation, as it were — and average behaviors over what one hopes is a spanning set of butterfly - wing perturbations to assess whether or not the resulting system trajectories fill the available phase space uniformly or perhaps are restricted or constrained in some way.

The growing divergence between models and observations even on a global average, and the lack of mathematical foundation to the statement that the fluctuations between runs of the same models and between runs of different models «are noise» [73] forbids their use as justification of economic or political decisions.

The fluctuations around this average are noise for the models

The growing divergence between models and observations even on a global average, and the lack of mathematical foundation to the statement that the fluctuations between runs of the same models and between runs of different models «are noise» [Monckton, 29 July 2014] forbids their use as justification of economic or political decisions.

In short, the global climate models used in the IPCC reports have been very good at predicting the underlying human - caused global surface warming trend, beneath the short - term noise which will average out to zero over time.

If cloud changes are associated with natural internal variability which the: models generally consider «unforced variations» then I guess we can pretend that variability averages to zero over a reasonable time frame and ignore it as noise, even though we are not particularly sure what is a reasonable period of time in climate.

In a realistic model with internal variability, you need to do this multiple times and then average to knock down the noise so as to isolate the forced response if you are trying to be precise.

For independent realisations, the natural variability noise is reduced by the ensemble averaging (averaging to zero for a large enough ensemble) so that -LCB- T -RCB- is an improved estimate of the model s forced climate change Tf.

It combines beautiful and comfortable build quality, better - than - average active noise cancellation, and the best sound quality our panelists have ever heard from a Bluetooth headphone model.
