The problem with an arbitrary significance level is you are abdicating your respondibility to determine FOR YOUR PARTICULAR EXPERIMENT what a significant result is. This is both a statistical and field dependent process that is too complex to be adequately assessed by a simple apriori alpha (if nothing else it ignores beta and especially in medical trials or tests the risk to the patient of an alpha or beta error is not symmetric). So the preferred methodology in the fields of biology I currently work in is to report your exact p value for your test(s) and then discuss that value in reference to your biological hypothesis. Stating that your value is significant/not significant does not add any additional information.
If you performed two experiments that resulted in the following two p values, exp. 1: p = 0.049, exp. 2: p = 0.051 what would you conclude?
Not sure as the HDMI is limited to stereo (or maybe 2.1) tracks.
Interesting Mike. I have decided not to go the Amarra 4 upgrade route. The problem I have with the Oppo is it does not have an SPDIF input.
The level of significance is arbitrary because as you stated, it can be any value. Therefore you simply calculate the p value, which is the actual probability of making a Type I error. The whole idea of a significance level is archaic. It's only usefulness is in introductory classes and to explain what an actual probability value of a test statistic is. Confidence levels are also arbitrary as you can calculate them for any level of confidence between 0 and 1. At least in biology we are rapidly moving away from the idea of statistical significance. The Bayesians have given up on it a long time ago.
Now back to your regularly scheduled program.
Actually a significance level, or more correctly an alpha level (the type I error rate) is not actually necessary. One can simply calculate the probability of the test and utilize it in the context of the original hypothesis without the need of a totally arbitrary alpha level.
Totally agree. I feel no real need for an upgrade from the 2 so waiting or things to play out will not be painful.
Also agree. More horsepower interests me but increased display resolution is not something I personally have a need for.
^^This although I use my air a few times a week. Also I will not be an early adopter and will wait as I am currently very happy with the performance of the iPad2
My second beer at FFF the other night was Rune Priest, their Belgian Ale which used Sorachi Ace Hops. It was an excellent beer and the hop flavor was unique, in a good way. Sounds like this will be an interesting brew.
Well you pretty much nailed it right there.
In this case Jude is pretty much painting himself as clueless. His argument really has no logic to it. If instead he argued that the circuits of Spritzer's WES and the Woo WES might not be the same since they are not based upon a single schematic would at least be somewhat tenable. To argue that it is not a WES because it is not built by Woo. Yeah not so much. But in reality, I could give a shit.
Arrived home after a great time at FFF with Al, Bryan, Allison, John, Mike and Debbie. Thanks for nice parting gifts Al and Mike and the great breakfast Debbie.
