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.
App Stochastic Queue For Android
The application is model of working of 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.
app is designed to store many samples of single-channel queue system
model work as single-channel queue system for mass service
waiting and service time are stored and processed as samples of random variables
simulate waiting time and staying in the system
random variables are simulate by probability distributions: - Exponential; - Uniform; - Erlang's; - Weibull's; - Truncated normal or Regular flow
calculate -average value, - standard deviation, - skewness and kurtosis; and other
results data can be exported and sending by Internet
create, delete and selection of a folder for storage data results
