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

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

I have a file that looks that this:
820 890 530
1650 1600 1800

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

grdinfo
GRDINFO(l) GRDINFO(l)
NAME
grdinfo - Get information about the contents of a 2-D grd file
SYNOPSIS
grdinfo grdfiles [ -C ] [ -D ] [ -F ] [ -L1 ] [ -L2 ] [ -M ] [ -V ]
DESCRIPTION
grdinfo reads a 2-D binary grd file and reports various statistics for the (x,y,z) data in the grdfile. The output information contains the
minimum/maximum values for x, y, and z, where the min/max of z occur, the x- and y-increments, and the number of x and y nodes, and
[optionally] the mean, standard deviation, and/or the median, L1 scale of z, and number of nodes set to NaN.
grdfile
The name of one or several 2-D grd files.
OPTIONS
No space between the option flag and the associated arguments.
-C Formats the report using tab-separated fields on a single line. The output is w e s n z0 z1 dx dy nx ny [ x0 y0 x1 y1 ] [ med scale
] [ mean std rms] [n_nan]. The data in brackets are output only if the corresponding options -M, -L1, -L2, and -M are used, respec-
tively.
-D Report grid domain and x/y-increments using dd:mm:ss[.fff] notation [Default is decimal]. Does not apply to the -C option.
-F Report grid domain and x/y-increments world mapping format [Default is generic]. Does not apply to the -C option.
-L1 Report median and L1 scale of z (L1 scale = 1.4826 * Median Absolute Deviation (MAD)).
-L2 Report mean and standard deviation of z.
-M Find and report the location of min/max z-values, and count and report the number of nodes set to NaN, if any.
-V Selects verbose mode, which will send progress reports to stderr [Default runs "silently"].
EXAMPLES
To obtain all the information about the data set in file hawaii_topo.grd, try
grdinfo -L1 -L2 -M hawaii_topo.grd
