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

calc_spline
calc_spline(3alleg4) Allegro manual calc_spline(3alleg4)NAME
calc_spline - Calculates a series of values along a Bezier spline. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
void calc_spline(const int points[8], int npts, int *x, int *y);
DESCRIPTION
Calculates a series of npts values along a Bezier spline, storing them in the output x and y arrays. The Bezier curve is specified by the
four x/y control points in the points array: points[0] and points[1] contain the coordinates of the first control point, points[2] and
points[3] are the second point, etc. Control points 0 and 3 are the ends of the spline, and points 1 and 2 are guides. The curve probably
won't pass through points 1 and 2, but they affect the shape of the curve between points 0 and 3 (the lines p0-p1 and p2-p3 are tangents to
the spline). The easiest way to think of it is that the curve starts at p0, heading in the direction of p1, but curves round so that it
arrives at p3 from the direction of p2. In addition to their role as graphics primitives, spline curves can be useful for constructing
smooth paths around a series of control points, as in exspline.c.
