Base Statistic 4 for Android

About Base Statistic 4 for Android Android App

The app consists two components, one is processing samples of random variables and the second calculator for the known statistical distributions. The app has ad banners.

PROCESSING SAMPLE OF RANDOM VARIABLES

Component processing sample of random variable is designed to store (edited, deleted, renamed) only one sample of random variable , 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 and smoothed histogram of sample; and others.
The AppliedStatistics4 application has the same features as BaseStatistics4 but can handle multiple samples.
Sample, results of processing and histogram can be saved in database (Sqlit). Tables with these data can be exported for printing for example, by means of Sqlit browser. Perform the function "Init DB"( initiate DB) from the menu of boot activity, when booting the application for first time With the implementation of this function is loaded and a list of some samples.
The component Distributions is calculator for the known statistical distributions:
Normal distribution,
Chi-square distribution,
Student distribution,
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.
When booting the application BaseStatistic4 displays a list of samples introduced by BaseStatistic1. So to work with the application BaseStatistic4 prerequisite is installed application BaseStatistic1, which creates the content provider.
