Hi!
Suppose I have a dataset as follows
pd = c(10,7,10,11,7,11,7,6,8,3,12,7,7,10,10)
I wish to calculate the mean, standard deviation, median, skewness and kurtosis
i.e. regular standard statistical measures.
average = mean(pd)
stdev = sd(pd)
median = median(pd)
skew = skewness(pd)
kurt = kurtosis(pd)
Q. No (1)
How do I get these at a stretch using some R package? I came across moments and
e1071 package, but I am not sure which one to use and how?
Q. No. (2)
Many times I came across the command
set.seed(1234)
What is the significance of this command. I understand this is related to
random number generation. But what does it do?
Thanking in advance
Amelia
