R help - Nov 2007 - Statistics for the Grouped data

Hi R,

 

I have the data,

 

Value

0

1

2

3

4

5

6

Frequency:

258

125

106

94

85

12

5

 

Say:

Value=c(0,1,2,3,4,5,6)

Frequency=c(258,125,106,94,85,12,5)

 

 

In R, how can I find the mean, variance, skewness and kurtosis for this
grouped data? Is there a direct way of handling this type of grouped
data, instead of writing the code for calculating these statistics?

 

Thanks for your help,

Shubha

Hi Shubha,  

Have a look at the Hmisc package and try ?wtd.mean  as
the help command. This may be what you need.  Also you
might want to look at ?summerize in the Hmisc package.
