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}'

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
I need to calculate the RMS deviation for each data line, i.e. column 1 relative to... (12 Replies)
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:
input data:

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

mintegrate - evaluate average/sum/integral/derivative of 1-d numerical data
SYNOPSIS
mintegrate [OPTION]... [FILE]
DESCRIPTION
mintegrate is a program to compute averages, sums, integrals or derivatives of numerical 1-d data in situations where ultimate numerical
precision is not needed.
OPTIONS -a compute mean value (arithmetic average) and standard deviation
-c compute integral on closed x-data interval; In case that dx is not specified by the '-d' flag, the data are supposed to be from an
irregular x-grid, and dx is computed separately for every x-interval. The integral is computed by the trapezoidal rule.
-d <float>
compute integral on open x-data interval with the specified dx; Can be used also in combination with '-D' and '-c'.
-D compute difference btw. numbers or derivative of the y-data; In the default scenario where x- and y-data column are same, the dif-
ference btw. the current and the previous data value will be output. In this case when '-d' is defined as 0, the x-data value will
be print out in front of the calculated difference. If x-and the y-column are different and if the x-data resolution is not defined
or it is !=0, then the derivative of the y-data is calculated. When the x-data resolution is constant, specify it explicitly by '-d'
to achieve a higher numerical precision by a 'leapfrog' algorithm.
-x <int>
x-data column (default is 1). If 0, the x-range is an index;
-y <int>
y-data column, where y=f(x) (default is 1)
-r x_0:x_1
x-data range to consider
-s print out accumulated y_i sums: x_i versus accumulated f(x_i); In the case of a closed integral you have to specify also the x-data
resolution dx (see '-d' above).
-S compute the accumulated y_i-sums and add it to the output
-p <str>
print format of the result ("%.10g" is default)
-t <str>
output text in front of the result (invalid with '-s' or '-S'); A blank can be printed by using a double underscore character '__'.
-T run a self-test that the program is working correctly
-V print version number
--version
output version and license message
--help|-H
display help
-h display short help (options summary)
If none of the options '-a', '-D', '-d', or '-c' is used, then the sum of the provided data will be computed. Empty lines or lines starting
with '#' are skipped.
This program is perfectly suitable as a basic tool for initial data analysis and will meet the expected accuracy of a numerical solution
for the most demanding computer users and professionals. Yet be aware that, although the computations are carried with double floating pre-
cision, the computational techniques used for evaluating an integral or a standard deviation are analytically low-order approximations, and
thus not intended to be used for numerical computations in engineering or mathematical sciences for cases where an ultimate numerical pre-
cision is a must. For deeper understanding of the topic see http://en.wikipedia.org/wiki/Numerical_analysis.
