Really these functions do need to be addressed but it is rather daunting 
task to go through all these functions especially for the assigned 
criteria and given the 'duplicated' masked array functions. There are 
about 187 functions involved in stats modules - although some are 
deprecated and 'redefinition' of existing functions. Some of the 
functions are more utilities than stats functions and some functions are 
very dimension specific. For example, there is a tmean(a, 
limits=(min,max)) function that is essentially doing "a.compress((a>min) 
& (a<max)).mean()" because there is no axis option. Then there is a 
masked array function, trimmed_mean, that does have an axis argument.

However, I came to the conclusion that most of these have more problems 
than they are worth making my original idea worthless. So it would be 
better to have a clear plan for a proper set of statistical functions 
than just 'blindly fixing' the existing functions.
