Under theα=5% significance level, the identification rates of four models for the unknown samples are 90%, 80%, 100% and 100% in turn by means of NIR wave lengths, while, the rejection rates of four models are all 100%.
They are: credit and efficiency, level of variable and mathematical model, parametric test and nonparametric test, hypothesis test of mean and standard deviation, hypothesis test and analysis of variance, significant difference and non-significant difference, level of significance of correlation coefficient and osculation degree of correlation, statistics and physical education.
We get conclusions that suppose one area which is circled by left parts and statistic density curve is α_1 and the other area which is circled by right parts and statistic density curve is α_2, and α_1+α_2=α is level of significance, probability of making second kind mistake is indefinite and it has a definite dependent relation to parameter real value which is tested.
Stepwise multiple logistic regression analysis at 0.05 significant level with adjust ment of sex,smoking,alcohol drinking,systolic blood pressure,overweight,waist-hip ratio,serum triglyceride,serum total cholesterol covariates showed that the eNOS4a had no significant effect on p-CHD(P=0.427,OR=0.819,95%CI=0.500～1.341).
Stepwise multiple logistic regression analysis at 0.05 significant level with sex, smoking, alcohol drinking, and overweight covariates indicated that G894T mutation also having significant effect on P-CHD ( P= 0.01, OR= 2.25, 95%CI: 1.19- 4.26).
The frequencies of the Ter447 allele and Ser447Ter genotype were lower in NIDDM patients than those of controls (3.4% vs 7.6%;6.9% vs 15.0%). The differences were very close to the significant level (P=0.065 and P=0.057).
Results:The percentage of δ-band power showed no significant changes at the dose of 2 5mg/kg,but it increased more than one time,however it did not reached the significant level ( P >0.05) at the dose of 5mg/kg.
There was a significant positive correlativity in water absorption of gluten with protein content of dry gluten,the correlativity of standard flour and special flour reached up to 0. 05 and 0. 01 significant level respectively.
It is proposed that to testify the regression equation and the regression level,non-linear equation should be converted into linear equation and also that related coefficient,manifestation level and remaining standard difference rate should all be exploited for the same purpose.
Over 90.1% of Northern Eurasia, the χ2values satisfy the goodness-of-fit test at a significance level of α = 0.1.
The harmonic data analysis at a fairly high significance level revealed two close periods, P1= 3h.5372 ± 0h.0005 (amplitude 0m.4) and P2= 4h.367 ± 0h.001 (amplitude 0m.2).
The third period, P3= 20h.26 ± 0h.05 (amplitude about 0m.15), was found at a lower significance level.
Both models are inconsistent with the observed light curve, and can be rejected at the >amp;lt;2% significance level.
Bona fide identification (at a significance level greater than 90%) of compact moving groups based on kinematic data requires higher accuracy of the stellar spatial velocities (with errors no greater than 1-2 km/s in each component).
The separation of positive and negative muons in a giant shower by the geomagnetic field is observed at a very high level of significance 0.03%.
When the period of the sine-wave curve was allowed to vary in order to fit the data best, none of the statistical tests reached the level of significance required to dismiss the possibility of false-positive results.
Correlations were sought between these measurements using the Pearson product-moment correlation with a level of significance of p = 0.05 (two-tailed).
A decrease (-4.3%) in total body weight was also found in men with Parkinson's disease but the difference did not reach the level of significance.
The possibility of substituting the direct spectrophotometric method for amino acid analysis was statistically evaluated; it does not seem to be rejected at the highest level of significance,P≤1%.
HOCl is a strong oxidation agent produced at the significant level by neutrophils.
The approach developed by us has allowed detection of 9675 MIRs at a statistically significant level, which by 15% exceeds the MIR number revealed by all previous approaches.
A significant level of the specific signal was achieved by using the PCR-amplified DNA fragments of different length (200-400 bp) irrespective of the position of the tandem-binding site in their sequences.
A significant level of polymorphism between the majority of the populations studied was detected.
We detected 28 sources at a statistically significant level with fluxes above 1.4 mCrab in the energy range 18-60 keV.
One QTL exceeded experiment level and one QTL genome level significance thresholds.
Population-level significance of pollution effects on clam reproduction will depend on how contaminated the environment is over the entire reproductive season of the clams in Long Island Sound, and over how large a portion of the spawning grounds.
Specifically, PM-MM differences are used to perform individual probe level significance tests using the t-test.
The shaded regions show the 95% level significance according to the Student's t test of these differences.
