Descriptive Statistics of Grouped Data
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.
