I have this text file:
$ cat resultados.txt 10.8 12.1 14.2 14.8 19.4 8.62 9.73
Important: numbers are in rows, not in columns.
I want to perform the geometrical operation:
e((l(number1)+l(number2)+l(numbern))/n)
How can I do that?
here is another alternative for geometric mean
$ awk 'BEGIN{p=1} {p*=$0; n++} END{print p^(1/n)}' file 12.3846
or, with NR
$ awk 'BEGIN{p=1} {p*=$0} END{print p^(1/NR)}' file
Your question would be clearer if you provided the expected output given that input but is this what you're looking for?
$ awk '{sum+=log($0)} END{if (NR) print sum, sum/NR, exp(sum/NR)}' file 17.6152 2.51646 12.3846
