I have written a code to work on a document with 50 columns of data to calculate the RMSD of each column of data relative to the last column of data.
The script is pretty primitive, and involves 50 different variables. Is there a way I could make it automatic by simply incrementing the n_x variable instead of having to define the 50 variables manually. Also, instead of defining the last column as $50 how do I do it with an $NF?
I have a CSV file that looks like
0,0,0,0,1,0,1,0,1,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,2,0,0,0,0,0,0
10,11,7,0,4,12,2,3,7,0,11,3,12,4,0,5,5,4,5,0,8,6,12,0,9,3,3,0,2,7,8

Hi all,
I am new to shell scripting and wanna calculate the mean and standard deviation using shell programming.
I have a file with letters that are repeating and their corresponding duration
a 0.32
a 0.89
aa 0.34
aa 0.23
au 0.012

Hi all,
I want to calculate the standard deviation for a column (happens to be column 3).
Does any know of simple awk script to do this?
Thanks (1 Reply)
Hi I want to use awk to print avg and st deviation but it does not go into a file for column 1 only.
I can do average and # of records but i cannot get st deviation.
awk '{sum+=$1} END { print "Average = ",sum/NR}'

Hi all,
I need to find the standard deviation of each column of a dataset below for each hour. The data is given in 5 second intervals as shown below

Hi All,
I want someone to modify the below script from this forum so that it can be used for all columns in the file( instead of only printing column 3 mean and standard deviation values). I don't know how to loop around all the columns.

Hi,
I have a file containing 100,000 rows-by-120 columns and I need to compute for the standard deviation for each row. Any idea on how to calculate row-wise standard deviation using awk? My sample data looks like this:

Hello there,
I found an elegant solution to computing average values from multiple text files
awk '{for (i=1;i<=NF;i++){if ($i!~"n/a"){a+=$i}else{b++}}}END{for (i=1;i<=FNR;i++){for (j=1;j<=NF;j++){printf (a/(3-b))((b>0)?"~"b" ":" ")};printf "\n"}}' file1 file2 file3

I have a file that looks that this:

I would like to output the mean and standard deviation of each row so that my final output would look like this

Hello Team,
I am using the following awk script to calculate the SMA (Single Moving Average) for an specific period but now I would like to include the standard deviation output.
Could you please help me to modify this awk shell script

test::use::ok
Test::use::ok(3) User Contributed Perl Documentation Test::use::ok(3)NAME
Test::use::ok - Alternative to Test::More::use_ok
SYNOPSIS
use ok 'Some::Module';
DESCRIPTION
According to the Test::More documentation, it is recommended to run "use_ok()" inside a "BEGIN" block, so functions are exported at
compile-time and prototypes are properly honored.
That is, instead of writing this:
use_ok( 'Some::Module' );
use_ok( 'Other::Module' );
One should write this:
BEGIN { use_ok( 'Some::Module' ); }
BEGIN { use_ok( 'Other::Module' ); }
However, people often either forget to add "BEGIN", or mistakenly group "use_ok" with other tests in a single "BEGIN" block, which can
create subtle differences in execution order.
With this module, simply change all "use_ok" in test scripts to "use ok", and they will be executed at "BEGIN" time. The explicit space
after "use" makes it clear that this is a single compile-time action.
