Friday morning ramble, #372

Liberty and reason are fighting back this week against the faith-based green-mongering bulldozer, as several stories from around the ‘net celebrate.
This week’s most interesting disclaimer:
_quote This paper has not been peer-reviewed by Phil Jones, Keith Briffa, Mike Mann, or any IPCC lead author!

Hehe, that's a funny youtube animation of the Hockey Stick oracle Michael Mann.

For those here who haven't read the original hockey-stick temperature reconstruction graph controversial paper, here it is shown below:

Global-scale temperature patterns and climate forcing over the past six centuries

The technique that they used is called Principal Component Analysis (PCA), which is a linear multivariate statistical technique. It is a popular method in data analysis. If you're using a text search engine, like something searching for a book in a library, this is what the engine is using, PCA. The PCA is based on a linear algebra algorithm called SVD (singular value decomposition), which is also popular in scientific, statistical & engineering analysis. Face recognition software uses it (as one of the many) and so other countless applications.

Since PCA is linear, it is susceptible to giving misleading results since the real world is non-linear. There has been many extensions to the standard linear PCA to make it non-linear, such as Kernel PCA, this is the version that I use in my development (which is still largely still unknown to many statisticians, because these nonlinear PCA variants are published in IEEE, SIAM, ACM journals and not statistics). One version that I am interested to implement is the Dynamic PCA, because the model updates itself incrementally over time, which is good in real time application.

Anyway, back to Mann and his hockey stick. I sent him an email once (no reply from him and I shouldn't be surprised), just to advise him on non-linear methods as I have mentioned above, because the standard PCA he used is unreliable. Yep, unreliable according to researchers in the domain of pattern recognitions (not according to falafulu), and that's why those researchers (pattern recognition experts) have developed non-linear versions because they found that PCA has severe limitations. Also check out their choice of low-pass filter that they used in their paper. There was no explanation of what filter they used and why they used it.

I can only guess that Prof. Mann didn't reply back and thanked me because he felt ashamed that he didn't know it himself. I am 100% confident that he never heard of non-linear PCA variants till the day that I alerted him to the availability of those robust methods.

Ok, the hockey stick is a statistical model (blind-faith) and not a physics model. There are lots of arguments about debunking it by Stephen McIntyre , et al and also the counter-argument put forward by Mann's supporters. These arguments are not important to me.

What I found amazing is that they tried and interpret their PCA reconstruction to fit in with the GCM. This is largely being ignored by both warmists and anti-warmists. Statistics is not physics as I have said many times before, and the interpretation of Mann et al, results in their paper (using PCA), was unscientific to me. Physics model that represent reality, derive what to expect from observations before those are being confirmed rather than tweaking or interpreting the data to fit the model which has been formulated as a priori. Mann's et al original paper did exactly that. Interpreting the PCA reconstruction to agree with the prediction of the GCM.

Ok, I think that's enough global warming explanation for me this week. Perhaps its time for a beer, because it is nice and sunny.

To Simon Power

Congratulations on abolishing the defence of provocation.

You are highly successful at what you do; and no doubt viewed as a strong and dependable man by many.

You are now assured of votes from gay men, and the emotionally weak.

May your career prosper.

"The Defence of Provocation."

1 It was never an absolute defence. It was a method to negate intent and thereby reduce a murder charge to manslaughter.

2 Its misuse in the Weatherston circus was not sufficient a ground to remove it from the Crimes Act 1961.

3 In NZ we do not have degrees of homicide as in other jurisdictions.

I suggest that the removal of provocation ought to have been a component of an overall re-assessment of homicide. Parliament is a repository for failed lawyers, and they've acted unthinkingly once again!

Faversham.

Q: Where does monetary inflation come from? A: World's banks hold very low real reserves. Major banks in Japan, US, Germany, Spain, & Italy fail the 8pc safety level. Which means for every dollar they actually hold, they’re lending out well over twelve, and some as much as twenty!
http://bit.ly/7ygpzf


Bank's cash reserve ratio is something different from the capital ratio that The Telegraph's article is talking about.

S&P's risk adjusted capital ratio (RAC) is crudely a ratio between equity and assets. Where the assets for a bank are the loans it has made.

The Cash reserve ratio in terms of the balance sheet would be demand deposits (a liability) over Cash + Reserves at the Central Bank (an asset).

The RAC ratio has not much to do with fractional reserve as even banks with 100% cash reserves could have a low RAC ratio.

I like that, Anonymous. "Parliament is a repository for failed lawyers".

Not surprising then that Simon Power is unable to grasp the difference between the 'thought' of provocation and the 'act' of defence.

Americans are suffering from PTSD of 9/11 trauma. What's ailing Kiwis?

I don't know. But, if continual disappointment leads to dulled anger, what more will stir Kiwis into acting?

The thought of absorbing 90 million over the next 3 years? Who's laughing silly at this low figure?

Will this thought provoke Kiwis into action?

But it wasn't misused, it failed miserably, Weatherston is in jail and is the most hated man in the country.
