waiting to find out what's gonna happen today.
-
trying not to go insane.
-
I love cophee!
-
sitting at camp hunter liggett in california. bored. come play with me.
-
packing and going to bed soon.
-
if you cut the correct way you miss the tendons... whats with goths today? can't even kill 'em selves right ;o)
-
*grabs towel* you are supposed to cut your own wrists, not mine!
-
waking up. about to shower, then go get a hair cut.. stupid army ;o) then go to werk.
-
what we have here is a failure to communicate, some men you just can't reach, which is the way he want's it, well.. he gets it! *hands phee a pen knife*
-
Good mourning gothie poo's the cophee shop is open for... well whatever you want.
-
have you been watching x-men again?
-
doing a very little bit of house cleaning before bed, and watching the allstar game.

no this is accurate: "Accuracy" redirects here. For the song "Accuracy" by The Cure, see Three Imaginary Boys In the fields of science, engineering, industry and statistics, accuracy is the degree of conformity of a measured or calculated quantity to its actual (true) value. Accuracy is closely related to precision, also called reproducibility or repeatability, the degree to which further measurements or calculations show the same or similar results. The results of calculations or a measurement can be accurate but not precise; precise but not accurate; neither; or both. A result is called valid if it is both accurate and precise. The related terms in surveying are error (random variability in research) and bias (non-random or directed effects caused by a factor or factors unrelated by the independent variable). Contents [hide] 1 Accuracy vs precision - the target analogy 2 Accuracy and precision in logic level modeling and IC simulation 3 Quantifying accuracy and precision 4 Accuracy in biostatistics 5 References [edit] Accuracy vs precision - the target analogy High accuracy, but low precision High precision, but low accuracyAccuracy is the degree of veracity while precision is the degree of reproducibility. The analogy used here to explain the difference between accuracy and precision is the target comparison. In this analogy, repeated measurements are compared to arrows that are fired at a target. Accuracy describes the closeness of arrows to the bullseye at the target center. Arrows that strike closer to the bullseye are considered more accurate. The closer a system's measurements to the accepted value, the more accurate the system is considered to be. To continue the analogy, if a large number of arrows are fired, precision would be the size of the arrow cluster. (When only one arrow is fired, precision is the size of the cluster one would expect if this were repeated many times under the same conditions.) When all arrows are grouped tightly together, the cluster is considered precise since they all struck close to the same spot, if not necessarily near the bullseye. The measurements are precise, though not necessarily accurate. Further example, if a measuring rod is supposed to be ten yards long but is only 9 yards, 35 inches measurements can be precise but inaccurate. The measuring rod will give consistently similar results but the results will be consistently wrong. However, it is not possible to reliably achieve accuracy in individual measurements without precision — if the arrows are not grouped close to one another, they cannot all be close to the bullseye. (Their average position might be an accurate estimation of the bullseye, but the individual arrows are inaccurate.) See also Circular error probable for application of precision to the science of ballistics. [edit] Accuracy and precision in logic level modeling and IC simulation As described in the SIGDA Newsletter [Vol 20. Number 1, June 1990] a common mistake in evaluation of accurate models is to compare a logic simulation model to a transistor circuit simulation model. This is a comparison of differences in precision, not accuracy. Precision is measured with respect to detail and accuracy is measured with respect to reality. Another reference for this topic is "Logic Level Modelling", by John M. Acken, Encyclopedia of Computer Science and Technology, Vol 36, 1997, page 281-306. [edit] Quantifying accuracy and precision Ideally a measurement device is both accurate and precise, with measurements all close to and tightly clustered around the known value. The accuracy and precision of a measurement process is usually established by repeatedly measuring some traceable reference standard. Such standards are defined in the International System of Units and maintained by national standards organizations such as the National Institute of Standards and Technology. Precision is usually characterised in terms of the standard deviation of the measurements, sometimes called the measurement process's standard error. The interval defined by the standard deviation is the 68.3% ("one sigma") confidence interval of the measurements. If enough measurements have been made to accurately estimate the standard deviation of the process, and if the measurement process produces normally distributed errors, then it is likely that 68.3% of the time, the true value of the measured property will lie within one standard deviation, 95.4% of the time it will lie within two standard deviations, and 99.7% of the time it will lie within three standard deviations of the measured value. This also applies when measurements are repeated and averaged. In that case, the term standard error is properly applied: the precision of the average is equal to the known standard deviation of the process divided by the square root of the number of measurements averaged. Further, the central limit theorem shows that the probability distribution of the averaged measurements will be closer to a normal distribution than that of individual measurements. Get it?

trying to motivate myself to clean my house... again

that was seriously the most serious of posts

there is a bottle of wine that has been in my fridge for so long that it was pointed out to me that it is entirely possible it's turned back in to grapes. I'm sorry for the terrible grammer in the last sentance.

Best "drunk" Drink? Taste Vs Strength
odims_sphere replied to Troy Spiral's topic in Health & Well-Being
wine gives me the most creative drunk. I like to drink wine and write music. -
Song that describes your mood right now
odims_sphere replied to saechalyn's topic in Music Discussion
apoptygma berzerk - Mourn Lost in the depths The depths of your eyes I couldn't resist Why should I? I want to relax I want to feel free I want to be you You want to be me I look at you I look at your face Reach for my hand, just in case Forever with you You mourn I can see Now I am you Do you want to be me? Why are you always hiding? Why are you always mourning?
