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
au 0.26... (4 Replies)
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)
awk '{ gsub(/....=/,""); print }' want.dat >final.dat
the above awk command which removes all the chars before and including '=' on the entire row. --thats what it meant be.:)
but i need to remove text on column-wise on each row.
many thanks,
EM

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

Hello all, I need to compute a row-wise average of files with a single column based on the pattern of the filenames. I really appreciate any help on this. it would just be very difficult to do them manually as the rows are mounting to 100,000 lines. the filenames are as below with convention as... (2 Replies)
Hi All,
I have the following time stamp data in 2 columns
Date TimeStamp(also with milliseconds)

gcomp
GCOMP(1) General Commands Manual GCOMP(1)NAME
gcomp - do computations on a graph file.
SYNOPSIS
gcomp [ -amilh ][ +variable value .. ][ file .. ]
DESCRIPTION
Gcomp reads each graph file in sequence and computes the specified calculations. The type options are as follows:
-n Print the name of each curve.
-a Print average and standard deviation of each curve.
-m Print minimum and maximum for each curve.
-i Print Romberg's approximation to the integral of each curve.
-l Print the slope, intercept, and correlation coefficient using the least squares method of linear regression.
-h Do not print a header in the output.
The calculations will be displayed as columns in the order they are specified on the command line. If no files are given, the standard
input is read.
Variables can be set explicitly with +variable value options. The only truely useful variables for this program are xmin and xmax. They
determine boundaries for the calculations.
EXAMPLE
To compute the approximate integral of sin(x)/log(x) from 2 to 4:
gcomp -i
A(x)=sin(x)/log(x);
Anpoints=100;
xmin=2;
xmax=4;
