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

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 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

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

NAME
pbm2ppa - convert portable bitmap (PBM) to HP's Printing Performance Architecture (PPA) file format
SYNOPSIS
pbm2ppa [options] [ <infile] > [ <outfile]> ] ]
DESCRIPTION
Reads portable bitmap (PBM) format as input. Outputs a stream suitable for processing by Hewlett-Packard's range of Printing Performance
Architecture (PPA) printers. pnm2ppa supports the HP 710c, 712c, 720c, 722c, 820c, and 1000c series printers.
(Portable bitmap (PBM) format output can be produced from PostScript(tm) input by the GhostScript driver "pbmraw".)
OPTIONS
infile Input file infile is either a path to a file or device, or '-' to indicate stdin (defaults to stdin)
outfile
Output file outfile is either a path to a file or device, or '-' to indicate stdout (defaults to stdout)
-b bottommargin
Sets the bottom margin bottommargin in units of 1/600 inches (e.g., -b 150 = 0.25")
-d Displays the current configuration
-f configfile
Overrides reading the configuration from /etc/pnm2ppa.conf, and uses configfile instead.
-h Displays program usage
-l leftmargin
Sets the left margin leftmargin in units of 1/600 inches (e.g., -l 150 = 0.25")
-r rightmargin
Sets the right margin rightmargin in units of 1/600 inches (e.g., -r 150 = 0.25")
-s papersize
Sets the paper size. Possible values for papersize are a4 (A4), letter or us (US Letter, 8.5"x11"), and legal (US Legal, 8.5"x14").
The default is US Letter.
-t topmargin
Sets the top margin topmargin in units of 1/600 inches (ie -t 150 = 0.25")
-v printertype
Selects the printer model. Possible values of printertype are: 710, 712, 720, 722, 820 and 1000. The default is the HP DeskJet 7X0
Series (710, 712, 720, 722).
-x xoffset
Sets the x-offset xoffset from the left of the page. Units are 1/600 inches
-y yoffset
Sets the y-offset yoffset from the top of the page. Units are 1/600 inches
NOTES
The configuration file is read in first. Command line arguments then modify the resulting definitions.
The -x and -y options accumulate. The -v option resets all definitions back to an inbuilt default for that printer and should be used
before subsequent -b -l -r, -t, -x, and -y arguments.

HISTORY
This program was written by Tim Norman. It originally supported black and white output on the 820 series. This program is almost obsolete;
its successor pnm2ppa will support color printing.
BUGS
This is a stable driver, but does not support color printing.
