While this procedure does not require that the random variables be normally distributed, one must estimate a parameter that is a function of the kurtosis of the underlying distributions. Simulation results indicate that REML-based confidence interval methods outperform other well-known methods in the ...
Sample correlation refers to the measure of the strength and direction of a linear relationship between two variables, calculated using a sample data set. It is represented by the correlation coefficient (rxy) and is used to determine the degree of association between the variables. ...
It can be hard to find the perfect sample size for statistically sound results. Here we reveal methods and tools for effective sample size determination.
These intervals can be viewed as random intervals , i.e., as samples from the interval-valued random variable. In such situations, instead of the exact value of the sample statistics such as covariance C x , y , we can only have an interval C x , y of possible values of this ...
ulcer_recurrence.sav.This file contains partial information from a study designed to compare the efficacy of two therapies for preventing the recurrence of ulcers. It provides a good example of interval-censored data and has been presented and analyzed elsewhere16. ...

We present the problem of the confidence interval estimation for excess risk (Y/n-X/m fraction), a parameter which allows evaluating of the specificity of an association between predisposing or causal factors and disease in medical studies. The parameter is computes based on 2x2 contingency table...
The inversion principle and monotonicity property of the proposed formulations are used to describe alternative approaches to the exact interval estimation, power calculation, and sample size determination for correlation coefficients. 展开 关键词: multiple correlation partial-multiple correlation simple ...
Write your data analysis plan; specify specific statistics to address the research questions, the assumptions of the statistics, and justify why they are the appropriate statistics; provide references Justify your sample size/power analysis, provide references ...
The input parameters consists of furan, acidity, moisture, IRT, dielectric strength, tan delta and DGA; each is characterized by two variables, i.e., its magnitude and change rate. If the database has a large volume, the FL model yields more reasonable results. Nevertheless, only three ...
