Component processing samples of random variables is designed to store (edited, deleted, renamed) samples of random variables, to calculate their basic statistical characteristics as the: -average value; - standard deviation; - skewness and kurtosis; - to calculate confidence intervals of the average value; - variance and standard deviation; - check whether the sample is from normal or uniformly distributed random variable using criterion of Pearson; - check whether the sample is from normal, uniformly and exponentially distributed random variable using criterion of Kolmogorov-Smirnov; - and zero skewness and kurtosis; - determined histogram of sample; - function testing of hypotheses related to the mean and standard deviation; and other.
The application has function for smooth distributions, this includes assets for visualization
adjusted( smooth) distributions related to the sample, not excluded from the Pearson's
and Kolmogorov-Smirnovr's criteria.
Samples, results of processing and histogram can be saved in database (Sqlit). Tables with these data can be exported and imported for saving and printing for example, by means of Sqlit browser..
The application has localization for: English, Bulgarian, French and German.
