Base Stochastic Queue For Android

Base de Stochastic Queue Pour Échantillons Traitement Android de variables aléatoires

BaseStochasticQueue application model work single-channel queue system for mass service. Allows the waiting and service time to be stored and processed as samples of random variables. Along with this application allows you to enter and process samples of random variables. The app has a calculator component known statistical distributions.

The app allows you to simulate waiting time and stay in the system for queuing. Input stream and service imitate by any of the following probability distributions: - Exponential; - Uniform; - Erlang; - Weibull; - Truncated normal or Regular flow (at regular intervals).

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) or save as .txt file, exported and send to e-mail. Data base 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.
