About Applied Statistic 4 - Android Android App

The application AppliedStatistic4 is part of a group applications, unites them that work with a content provider. The group also includes applications: AppliedStatistic1, AppliedStatistic2 and AppliedStatistic3. All are used for processing samples and histograms of random variables introduced by the application AppliedStatistic1.
The application AppliedStatistic1 is designed to store (edited, deleted, renamed) a list of samples of random variables. Two types are of the stored samples. One type is a histogram where for each importance of the random variable (X) is introduced and the number of observations (Y) of the random variable. The other type is only excerpts of the meanings of the random variable(X).
The list of samples of random variables is used by application AppliedStatistic4 for calculation and storage of basic statistical characteristics as: sample size; minimum and maximum velues; arithmetic mean of sample; mode of the sample; median of the sample; lower quartile of the sample;upper quartile of the sample; lower decil of the sample; upper decile of the sample; average absolute deviation of the sample; standard deviation of the sample - biased estimator; sample standard deviation - unbiased estimator; variance - biased estimator; sample variance - unbiased estimator; coefficient variance of the sample; range of variance of the sample; interquartile range of the sample; inter decile range of the sample; quartil deviation of the sample; decil deviation of the sample; sample skewness; sample kurtosis; check zero skewness is rejected or not rejected(small sample); check zero kurtosis is rejected or not rejected(small sample); normal distribution rejected or not rejected(small sample); check m-test:zero skewness rejected or not rejected(for large sample); check m-test:zero kurtosis rejected or not rejected(for large sample); check m-test: normal distribution rejected or not rejected(for large sample).
The application AppliedStatistic4 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 (AppliedStatistic4) also has functions to calculate (vizoalized and storing) of smooth distribution of these not rejected the relevant criteria. The application AppliedStatistic4 has and component called distributions. 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 AppliedStatistic4 displays a list of samples introduced by AppliedStatistic1. So to work with the application AppliedStatistic4 prerequisite is installed application AppliedStatistic1, which creates the content provider.
