I would like to write a script to extend this command to a general case:
Code:
BEGIN {s_0=0;n_0=0}{n_0++;s_0+=($51-$1)^2}END {print sqrt(s_0/n_0)}
i.e. so that
Code:
BEGIN {s_0=0;n_0=0}{n_0++;s_0+=($51-$1)^2}END {print sqrt(s_0/n_0)}
BEGIN {s_1=0;n_1=0}{n_1++;s_1+=($51-$2)^2}END {print sqrt(s_1/n_1)}
BEGIN {s_2=0;n_2=0}{n_2++;s_2+=($51-$3)^2}END {print sqrt(s_2/n_2)}
...
BEGIN {s_50=0;n_50=0}{n_50++;s_50+=($51-$51)^2}END {print sqrt(s_50/n_50)}
I already have a script that could loop over the variable s and n,
any ideas?

END(7) SQL Commands END(7)NAME
END - commit the current transaction
SYNOPSIS
END [ WORK | TRANSACTION ]
DESCRIPTION
END commits the current transaction. All changes made by the transaction become visible to others and are guaranteed to be durable if a
crash occurs. This command is a PostgreSQL extension that is equivalent to COMMIT [commit(7)].
PARAMETERS
WORK
TRANSACTION
Optional key words. They have no effect.
NOTES
Use ROLLBACK [rollback(7)] to abort a transaction.
Issuing END when not inside a transaction does no harm, but it will provoke a warning message.
EXAMPLES
To commit the current transaction and make all changes permanent:
END;
COMPATIBILITY
END is a PostgreSQL extension that provides functionality equivalent to COMMIT [commit(7)], which is specified in the SQL standard.
