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; - and zero skewness and kurtosis; - determined and smoothed histogram of sample; and others.
Samples, results of processing and histogram can be saved in database (Sqlit).
The application along with the above basic statistical characteristics has a check for normal and uniform distribution according to Pearson's criterion, check whether the sample is normal, uniform, exponentially, truncated normal, U-quadratic or reciprocal distributed random variable according Kolmogorov-Smirnov's criterion. This application also has functions to calculate of smooth distribution of these not rejected the relevant criteria. The application has and component called distributions. The component Distributions is calculator for the known statistical distributions:
Fisher distribution, and others.
The samples and results of processing can be saved in database (Sqlit). The tables with these data can be exported for printing for example, by means of Sqlit browser.
