Aimed at two-parameter exponential distribution, this paper discusses the interval estimation of its scale parameters in the case of incomplete data. By using the sample quantile which can effectively resist the contamination of outliers in samples, the paper constructs the pivot variable, deduces the...

Interval censored data arise naturally in large scale panel studies where subjects can only be followed periodically and the event of interest can only be recorded as having occurred between two examination times. In this paper we consider the problem of comparing two interval-censored samples....
we will not know the exact prevalence of the population as we do not study all members of the population. However, the sample study gives us an estimation which has lower and upper limits (informally ‘a range’, but we call ‘interval’ in Statistics...
Over the past decade SAA method has become a very popular technique in solving large-scale SP problems. The key idea of SAA approach in solving SP can be described as follows. A sample \(\xi _{1}, \ldots , \xi _{N}\) of N realizations of the random vector \(\xi\) is randomly...
In a classic example 2, 52 students were asked to rate the combinations of 15 situations and 15 behaviors on a 10-point scale ranging from 0="extremely appropriate" to 9="extremely inappropriate." Averaged over individuals, the values are taken as dissimilarities. behavior_ini.sav. This data...
Interpretation of Pearson's r As noted, the correlation coefficient provides information about the direction of the relationship and its strength. The range of possible values for the correlation coefficient provides an ordinal scale of the relationship's strength. In short, the correlation coefficient...
In statistics, a confidence interval is also known as a margin of error. Given a defined sample size, or the number of test results that were produced from identical repetitions, a confidence interval will report a particular range within which a certain
