Type: Package
Title: Descriptive Statistics of Grouped Data
Version: 0.1.1
Author: Partha Sarathi Bishnu <psbishnu@gmail.com>
Maintainer: Partha Sarathi Bishnu <psbishnu@gmail.com>
Description: Contains a function called gds() which accepts three input parameters like lower limits, upper limits and the frequencies of the corresponding classes. The gds() function calculate and return the values of mean ('gmean'), median ('gmedian'), mode ('gmode'), variance ('gvar'), standard deviation ('gstdev'), coefficient of variance ('gcv'), quartiles ('gq1', 'gq2', 'gq3'), inter-quartile range ('gIQR'), skewness ('g1'), and kurtosis ('g2') which facilitate effective data analysis. For skewness and kurtosis calculations we use moments.
