Help with identify gradient and the coefficient of determination of a straight line
Hi,
Do anybody experience using awk or perl command to identify gradient of a straight line and The coefficient of determination/R-square value of a chart (R2) ?
Below is my input file :
Desired Output :
From the input file, column 1 is item that I wanna to calculate their corresponding gradient and The coefficient of determination/R-square value.
Column 2, 3, 4, 5 is the value at 0, 3, 6, 10 seconds.
Column 6 and 7 in the desired output file is gradient and The coefficient of determination/R-square value of item in column 1.
As I know that microsoft excel able to calculate the gradient of a straight line and The coefficient of determination/R-square value of a scatter lot (R2)
when we display the equation of chart and display R-square value of a chart.
Because I have a long list of item wanna to calculate the gradient and The coefficient of determination/R-square value of a chart (R2).
Thus I just curious whether anybody experience to calculate it through awk/perl command.

Hi All,
I have a huge unix flat file delimted by @ at the end of the line. I need to find out if there is any line/s containing @ in between the line so that I can remove that and put the file for processing.
Thanks in advance for your help. (4 Replies)
Hi guys
I have an input file with multiple columns and and rows.
Is it possible to calculate correlation of certain value of certain No (For example x of S1 = 112) with all other values (for example start with x 112 corr a 3 of S1 = x-a 0.2 )

PLGRADIENT(3plplot) PLplot API PLGRADIENT(3plplot)NAME
plgradient - Draw linear gradient inside polygon
SYNOPSIS
plgradient(n, x, y, angle)
DESCRIPTION
Draw a linear gradient using colour map 1 inside the polygon defined by the n points (x[i], y[i]). Interpretation of the polygon is the
same as for plfill(3plplot). The polygon coordinates and the gradient angle are all expressed in world coordinates. The angle from the x
axis for both the rotated coordinate system and the gradient vector is specified by angle. The magnitude of the gradient vector is the
difference between the maximum and minimum values of x for the vertices in the rotated coordinate system. The origin of the gradient vec-
tor can be interpreted as being anywhere on the line corresponding to the minimum x value for the vertices in the rotated coordinate sys-
tem. The distance along the gradient vector is linearly transformed to the independent variable of colour map 1 which ranges from 0. at
the tail of the gradient vector to 1. at the head of the gradient vector. What is drawn is the RGBA colour corresponding to the indepen-
dent variable of colour map 1. For more information about colour map 1 (see the PLplot documentation).
Redacted form: plgradient(x,y,angle)
This function is used in examples 25,30.
ARGUMENTS
n (PLINT, input)
Number of vertices in polygon.
x (PLFLT *, input)
Pointer to array with x coordinates of vertices.
y (PLFLT *, input)
Pointer to array with y coordinates of vertices.
angle (PLFLT, input)
Angle (degrees) of gradient vector from x axis.
