## statistical

pertaining to or emanating from statistics.

statistical efficiency
between-test comparisons are based on the ratio of sample sizes required for the tests to have equal probabilities of detecting the same false null hypothesis; the more efficient test will have the smaller sample size.
statistical methods
procedures for collecting, classifying, summarizing, analyzing and making conclusions about, data. See also regression (4), path analysis, factor, discriminant analysis.
statistical significance

Q. What are the known statistics of Autism: Here is a question which needs a very detailed reply please. What are the known statistics of Autism: incidence, cost and ratio?

A. for more statistical information here are 2 sites:

and here is the CDC site link:

Q. Do you know if Propecia can truly stop hair loss and even grow back hair. do you have any statistics about it? do you know if there are any side effects to this medication?

A. it does work but there is some side affects, as in E.D. while you are on the med.

Q. What is the statistic number of women having breast cancer or under the threat of having breast cancer? where would i find a good , and reliable info about the disease ?

A. it is said that today 1 out of any 8 women will have breast cancer. there are also men who has breast cancer but the numbers are considerably lower.
about a good source of info- the site that doctoradhi gave you is pretty good, and you can use also the national medical library link:
http://www.nlm.nih.gov/medlineplus/breastcancer.html#cat22

good luck!

So, in order to solve the problem of statistical efficiency it is only necessary to use the following proposed approach: from an assembly of offer biddings B = {[B.
Therefore, we reopen the statistic efficiency issue: the anchored open-ended model shows greater statistical efficiency than the double-bounded model?
In order to demonstrate the relative gains of statistical efficiency in the use of the anchored open-ended model (AOE) when compared to the single-bounded (SB) and double-bounded models (DB), we will use a Monte Carlo experiment to enable the illustration of some alternative scenarios that can occur in camp.
In all cases there is a penalization to the anchored open-ended model with the intention of evaluating its statistical efficiency under unfavorable conditions.
1991) and Calia and Strazzera (2000) have found, the DB model is preferred to the SB in terms of statistical efficiency, measured by the SD and the amplitude of the interval that contains 95% of the samples' means.
The main idea of the proposed scenario 1 is to know until which point does the AOE model tolerate the loss of information and still be equivalent to the SB and DB models in terms of statistical efficiency.
Thus, considering the statistical efficiency aspect and the degree of precision in the estimates, the AOE model cannot be rejected as a viable alternative in the contingent valuation.
In this paper we argument that, if the awareness is towards statistical efficiency, the problem can be solved in a simple manner by using the AOE approach.
These gains in statistical efficiency from AMMI partitioning the treatment design are huge compared with the typical statistical efficiencies of 1.
00 0 ([dagger]) RMS PD based on model validation results and is a measure of predictive accuracy, greater accuracy with smaller RMS PD; statistical efficiency is the accuracy gain (in equivalent replications) afforded by a competing model relative to the standard model (AMMI-F); free observations are the required number of additional observations needed using AMMI-F to achieve the same accuracy gain (statistical efficiency) afforded by a competing model.
