I have large set of data.

Previously I was using matlab to plot CDF(cumulative distribution
function). But now very large set of data. matlab can't handle such
big data.

does anyone how can I calculate CDF using perl script.

Thanks.

## Re: calculate CDF

What happened when you typed

cumulative distribution function

into the little box at:

http://search.cpan.org/

## Re: calculate CDF

I found Math::CDF this module. but is there a place where I can find
example of this.

In Math::CDF

function:  pnorm(\$x)

what is \$x? how can I get value of \$x.

The name of the function is pnorm. \$x is a variable representing a
value. There is an example of using pnorm() in the SYNOPSIS section of
the Math::CDF documentation.

Math::CDF is a mathematical beast, not statistical, although is does
process formulas used in statistics. If you know the cummunulative
distribution function you are interested in, and it's included in the
module, then you can get the probability from the quantile (\$x) or the
quantile from the probability. But as another poster said, the module
doesn't process raw data.

Honestly, if the manual at http://search.cpan.org/dist/Math-CDF/CDF.pm
doesn't make sense to you this is probably not the module you need to

and if that isn't a case of RTFM, then i don't know what RTFM means.

## Re: calculate CDF

Not at all. The point is that it is a math stat module and if you are
not already familiar with those stat concepts you are probably looking
for something else, like a data analysis tool.

you still refered him to the manual and didn't hand hold him as you
years, maintains and posts the guideline, me thinks you have little
basis to bitch about. build up some credentials here before you accuse
anyone of anything.

It has been socially accepted for 20 years that trimming .sigs in
followups is good manners.

Then you are likely to be ostracized for your disregard toward others.

## Re: calculate CDF

Now *that* is certainly rejectable.

I really thought that the OP made no effort whatsoever to find
a solution to his problem before posting.

My response was colored in accordance with that thinking.

^^^^^^^

grammar.

nyuk.

## Re: calculate CDF

It's been a long time since I've looked around in this forum, nice to
know little has changed. If we deleted all the RTFM posts we'd cut the
size of the group in half :-)  I've always understood why one might
not choose to help a person, but to take the time to make sure he
knows you won't help has always seemed strange.
