Dealing with NAs in Lists
by Filipe Rodrigues da Costa
Dear All,
I'm trying to use the functions sd(x), and mean(x) in a list instead
of a series. From what I understood, these functions ignore NAs when
used in a series, but when used in a list they return NA if any
missing value.
I need to compute the cross-sectional mean and standard deviation and I
want NAs to be ignored, as they are in a series. Is there a simple way
of doing this? Basically a I have a list with 10 series and I want to
compute the standard deviations of all first observations, the standard
deviation of all second observations and so on. In R there is a way of
skipping NAs. Is there anything in Gretl?
Thanks in advance
