Is this a homework assignment? Homework and coursework questions can only be posted in this forum in a particular format described in special homework rules.
If this is homework, please repost it in the Homework & Coursework forum in the required format.
If not, please show us a sample of your input. Does it come from a file, is data manually entered, or what is the source? What is the format of the input data? Is it a CSV file using the pipe symbol as the field separator or is it some other format? Is there a heading line in the input?
Exactly what output you are trying to produce from your sample intermediate output (with the percentages you said you want, but did not describe).
What is your definition of a "blank space"? Is it an empty string? Is it a single <space> character? Is it a single character in the current locale's blank character class? Is it a string of one or more <space> characters? Is it a string of one or more characters in the current locale's blank character class? Is it a string of zero or more <space> characters? Is it a string of zero or more characters in the current locale's blank character class?
Please explain the logic used to determine when the output should be TRUE or FALSE and the logic used to determine when the output should be Positive or Negative.
If blank space is an empty string or a single <space>, why isn't the line in your intermediate output:
Code:
<BLANK>|<BLANK>|True Negative
be:
Code:
<BLANK>|<BLANK>|True Positive
instead. Shouldn't identical strings be Positive???
If blank space is a single <space> character, why isn't the line your intermediate output:
Code:
Binny's Sales|<BLANK>|False Negative
be:
Code:
Binny's Sales|<BLANK>|True Positive
instead. Shouldn't the <space> in the second field be considered a substring of the 1st field (matching the space in the middle of the 1st field?
What operating system and shell are you using?
What have you tried to solve this problem on your own?

This User Gave Thanks to Don Cragun For This Post:
As informed earlier, <BLANK> is just a empty space, I gave it initially. Now i hv replace with just space.
I have written below code for percentage calcualations, but m stuck with the logic for col1 and col2 with the scenarios below
1. if col1 string is similar col2 string or even the substring then it shul be TRUE POSITIVE
2. if col1 string is present and col2 string is not then it shul be false negative
3. if col1 string is not present and col2 string is present then it shul be false positive
4. if col1 string and col2 string not present then true negative
My 3rd o/p column shul be generated based on the i/p of col1 and col2 as shown above
My percentage calculation code is as shown below
Code:
Code:
for (i=1 ; i<cc; i++) {
p=(c[i]/NR)*100;
r=(i == 1) ? "" p : r OFS p;
}
print r
Exactly what output you are trying to produce from your sample intermediate output (with the percentages you said you want, but did not describe).
but you decided not to show us what output you want for percentages. The code that you say produces the percentages you want is not at all helpful since the code depends on three variables (cc, the array c, and the variable r) none of which have defined values that you have shown us. If this is awk code and these variables haven't been otherwise defined, this code goes through the for loop zero times and prints an empty line. I assume that you do not want an empty line, but I still have no idea what output you do want (other than that your percentages are to be calculated to two decimal places and that you want to include the line containing the headings in your input file in your calculations).
As I said before, there is not such thing as an empty space. From your latest sample input, we see that your use of the term empty space should be treated as a synonym for single space character, but if that is the case, you still need to explain why a single space in field two is not a subset of field 1 in the line:
Code:
Binny's Sales|
where the 8th character in field 1 is a single space character and field 2 is a single space character.
And, you still have not defined what string is similar means in your statement:
Quote:
1. if col1 string is similar col2 string or even the substring then it shall be TRUE POSITIVE
Please show us the EXACT output you are hoping to get from your script (including the percentages).
Please explain how we determine whether or not two strings are similar.
Please explain why a field that is a single space character is not a subset of a field containing a space character>.
And, please explain why two non-empty strings (each containing a single space) that are identical are classified under your rule #4 instead of being classified under your rule #1.
I urgently encourage you to think twice before posting your original problems and formulate with great care, supplying meaningful details. (Which, BTW, you have been asked before, answering:

Thanks a lot , sorry to trouble you folks with my wrong input. will make sure not to repeat again.
Step back for a second, forget all the context that you seem to imply, and look at your post#1 specification like the forum members do, not having any background on your problem. Do you think anybody could precisely understand what you request?

This matrix represents correlation values.
Is it possible to calculate the percentage of columns (a1, a2, a3) that have a value >= |0.5| and report the percentage that has positive correlation >0.5 and negative correlation <-0.5 separately. thanx in advance!

Hi,
I am looking for generic commands / scripts that could run across platforms especially on HP Itanium boxes to give me % of free OS parameters
For eg:

Free Total Swap Memory: 35%
Free Total CPU utilisation: 44%

Hi everyone
I am very new at awk but think that that might be the best strategy for this. I have a matrix very similar to a correlation matrix and in practical terms I need to convert it into a list containing the values from the matrix (one value per line) with the first field of the line (row... (5 Replies)
Hi all,
Is there a way to convert full data matrix to linearised left data matrix?
e.g full data matrix

how would you calculate percentage by per line? Given a column of 16 lines, grab each line and divide it by the sum of the entire column and multiply by 100?
thanks ... (8 Replies)
