I agree that the acentric method creates a PC1 that is more HS-shaped than otherwise.    From Wordnik.com.  [NAS Panel Excerpts: #1 PCs « Climate Audit] Reference

What is a mathematical description of the “type of object” that acentric PCA mines for?.    From Wordnik.com.  [Reconciling Zorita « Climate Audit] Reference

In the actual regression, how much impact numerically on HS index comes from this acentric method.    From Wordnik.com.  [NAS Panel Excerpts: #1 PCs « Climate Audit] Reference

Also, mice have acentric chromosome fusions since all their chromosome are acentric or acentric fusions.    From Wordnik.com.  [The Rise of Human Chromosome 2: Beyond the Deme - The Panda's Thumb] Reference

What VZ showed was minimal construction of hockey stick by acentric PCA versus centered PCA with Echo-G inputs.    From Wordnik.com.  [Reconciling Zorita « Climate Audit] Reference

The discourse on the acentric structure that myth itself is, cannot itself have an absolute subject or an absolute center.    From Wordnik.com.  [Dear readers...] Reference

For GENERAL investigations, you need to check methodology impacts e.g. acentric PCA or even some new issue on the end product reconstruction.    From Wordnik.com.  [Reconciling Zorita « Climate Audit] Reference

So fine: (1) define what a bad apple is, (2) show that it is present in the data field and (3) show how acentric versus centric PCA changes the mining of that “bad apple”.    From Wordnik.com.  [Reconciling Zorita « Climate Audit] Reference

The point is that acentric versus centric does not produce much of a difference with echo-G type input. you make the contention that it does with “hockey stick shaped” input.    From Wordnik.com.  [Reconciling Zorita « Climate Audit] Reference

The charge of anthropocentricity is explicitly addressed by the mystery approach, which attempts to give aesthetic appreciation of nature an “acentric” basis (Godlovitch 1994).    From Wordnik.com.  [Environmental Aesthetics] Reference

And I remain a bit concerned as to how much specifically the acentric PCA infleunces the overall result once you include MORE THAN PC1 and once you feed through "rest of Mannomatic".    From Wordnik.com.  [Reconciling Zorita « Climate Audit] Reference

Even if they are right, that the acentric method did no damage in MBH98, they still need to (1) acknowledge that it is wrong as a method and (2) make the assessment of how much it changes things mathematically.    From Wordnik.com.  [NAS Panel Excerpts: #1 PCs « Climate Audit] Reference

It had been known for some time that a crossover within the inverted segment in plants that are heterozygous for an inversion in one arm of a chromosome would result in a dicentric chromosome, and also an acentric fragment composed of all the chromatin from the distal breakpoint of the inversion to the end of the arm.    From Wordnik.com.  [Nobel Lecture The Significance of Responses of the Genome to Challenge] Reference

But at this point, regardless, I want to know why anyone would use acentric PCA haven’t heard one defense of it yet…other than it doesn’t matter…but noone says why you WOULD do it.    From Wordnik.com.  [Is Gavin Schmidt Honest? « Climate Audit] Reference

Sister chromatid recombination in cis-targeted cells can also lead to cell death associated with dicentric (two-centromere) and acentric (no-centromere) chromosomes (.    From Wordnik.com.  [PLoS ONE Alerts: New Articles] Reference

Unexpectedly, the trans group also exhibited a decreasing trend according to increasing inter - trans targeting, recombination results in formation of dicentric and acentric chromosomes, leading to cell death (.    From Wordnik.com.  [PLoS ONE Alerts: New Articles] Reference

Limited survival of those cells was depicted by the disappearance of the double-positive cells induced by OHT-treatment of Fig. 8A), indicating poor survival of these cells presumably by formation of dicentric and acentric chromosomes (.    From Wordnik.com.  [PLoS ONE Alerts: New Articles] Reference

4. Failure to describe the acentric PCA shows a) poor description of methods used and (b) that “giving the algorithm” may not be adequate in practice (should be in theory).    From Wordnik.com.  [Hasn't Mann's data "always" been available? « Climate Audit] Reference
