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

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

-I Only return the decimal portion of the final sum.
-c Print out the sum of each column.
-r Print out the sum of each row.
-x <n> Specify a comma seperated list of columns to print.
-y <n> Specify a comma seperated list of rows to print.
-s <string> Specify a string to use as a seperator for columns.
This defaults to be consecutive whitespace (s+).
-h Help: You're looking at it.
-V Increase verbosity.
