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}'
thanks (1 Reply)
Hello,
I am trying to create a awk script to calculate the simple moving average of two fields but I got only the result of the first field.
Could you please help me to fix this awk shell script
awk -F, -v points=5 '
{
a = $2;
b = $3;
if(NR>=points) {
total_a = 0;

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

I have a file with say 50 columns, each containing a whole lot of data.
Each column contains data from a separate simulation, but each simulation is related to the data in the last (REFERENCE) column $50

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

gpiv_t-avg
GPIV_T-AVG(1) General Commands Manual GPIV_T-AVG(1)NAME
gpiv_t-avg - Calculates time-averaged mean and variances of PIV data.
SYNOPSIS
gpiv_t-avg [-dn | --dir_name dir basename] [-df | --first_dir N] [-dl | --last_dir N] [-fb | --file_basename file basename] [-ff |
--first_file N] [-fl | --last_file N] [-fx | --file_prefix] [-h | --help] [-n | --none] [-p | --print] [-relrms] [-uv | --print] [-v |
--version]
DESCRIPTION
gpiv_t-avg calculates mean and variances from a series of piv data resulting into time-averaged values. If no parameters are defined at the
command line, standard parameters will be used that are defined in the script. This program does not use the parameter resources from libg-
piv.
Options-dn | --dir_name dir base-name
The dir base-name represents the directory name without its last number. It is supposed that the last number in the directory name
is a counter.
-df | --first_dir
Defines the counter N of the first directory number at which the analyses starts.
-dl | --last_dir
Last directory number N at which the analyses ends.
-fb | --file_base_name file base-name
The filename has to be given without its .piv extension. The file base-name represents the file name without its last number, before
the extension. If not -fx key is used, it is supposed that the last number in the file name is a counter. The output will be written
to dir base-name/file base-name.ta_mean.piv and dirname/filename.ta_sdev.piv at which mean values and variances are written respec-
tively or to dirname/filename.ta_U.piv and to dirname/filename.ta_V.piv if -uv is used.
-ff | --first_file
Defines the counter Nof first file number at which the analyses starts.
-fl | --last_file
Last file number N at which the analyses ends.
-fx | --file_prefix
Prefix numbering to file base name.
-h | --help
On-line help.
-n | --none
Suppresses real execution.
-p | --print
Prints parameters, command line options and input and output filenames to stdout.
-relrms
Prints relative rms, related to the absolute mean value.
-uv Writes U and v displacements/velocities to separate outputs.
-v | --version
Prints version information to standard output, then exits successfully.
