Describe the effect on the test statistic and the p-value when the sample size increases. Describe the effect on the p-value of increasing the sample size. Describe what happens to the confidence interval estim
Since the function relationship between fuzzy test statistic and fuzzy data under known population variance is different from that under unknown population variance, we use two methods to construct the membership function under known and unknown population variance environment respectively. An alternative p...
Note further that, as with the χ2 statistic, t values have their own statistical variations from one experiment to the next. Thus t values that are within a few percent of a critical value should be interpreted with caution. For most practical situations, P values can be read with sufficie...
example [h,pValue] = waldtest(___) returns the p-value of the hypothesis test, using any of the input arguments in the previous syntaxes. example [h,pValue,stat,cValue] = waldtest(___) returns the test statistic and critical value of the hypothesis test. exampleExamples...
One crucial notion involved in the Mann-Kendall test statistic is that of whether the difference between two measurements is greater than, equal to, or less than zero. This idea is in turn critically linked to the least count (i.e., the minimum possible measurement value) of the time serie...
The p-value is the probability of obtaining the observed test statistic as extreme as the one obtained, given the null hypothesis is true. In terms of rejection of the null hypothesis, it is the smallest level of significance, at which the...
It then calculates a p value (probability value). The p-value estimates how likely it is that you would see the difference described by the test statistic if the null hypothesis of no relationship were true.If the value of the test statistic is more extreme than the statistic calculated ...
The set of bins associating with the local peaks of test statistics (filtered by significant P-value) are called block boundaries and serves to partition a chromosome into blocks of dense chromatin interactions and gaps. In the third step, we define another test statistic, D i , to indicate ...
Uses the test statistic F to test for the significance of the regression model used • Can incorporate interaction terms • The value of F, the degrees of freedom and R2 should be stated • Can often be helpfully combined with the use of graphs or other descriptive statistics Read more...
We compare the value of our test statistic (65.03) to the Chi-square value. Since 65.03 > 7.815, we reject the idea that movie type and snack purchases are independent. We conclude that there is some relationship between movie type and snack purchases. The owner of the movie theater ca...
