Dear R helpers,
I have a data of 2102 observations (consisting of 0's also), to which I am
trying to fit Normal distribution using "lmom" pacakage. If I use Excel, its
easy to estimate the parameters of Normal distribution as simple mean and
standard devaition. The results I get if I use teh excel are as
Parameters of Normal distribution :-
Mean = 22986.44 and standard deviation = 223452.88
However, if I use the R code using the lmom package, I get the mean as 22986.39
and standard deviation as 39029.79.
Regards
Maithili
My R code is as follows. (Actually its a two line code, but since I am
representing data using 'c', the code looks too big.)
