Fsdb::Filter::dbfilealter - alter the format of an Fsdb file, changing the row/column separator
This program reformats a Fsdb file, altering the row ("-R rs") or column ("-F fs") separator. It verifies that this action does not violate the file constraints (for example, if spaces appear in data and the new format has space as a separator), and ...

Fsdb::Filter::db_to_csv - convert fsdb to the comma-separated-value file-format
Covert an existing fsdb file to comma-separated value format. Input is fsdb format. Output is CSV-format plain text (*not* fsdb)....

Fsdb::Filter::csv_to_db - convert comma-separated-value data into fsdb
Converts a comma-separated-value data stream to Fsdb format. The input is CSV-format (*not* fsdb). The first row is taken to be the names of the columns. The output is two-space-separated fsdb. (Someday more general field separators should be support...

Fsdb::Filter::dbpipeline - allow db commands to be assembled as pipelines in Perl
This module makes it easy to create pipelines in Perl using separate processes. (In the past we used to use perl threads.) By default (as with all Fsdb modules), input is from STDIN and output to STDOUT. Two helper functions, fromfile and tofile can ...

Fsdb::Filter::dbcolstats - compute statistics on a fsdb column
Compute statistics over a COLUMN of data. Records containing non-numeric data are considered null do not contribute to the stats (with the "-a" option they are treated as zeros). Confidence intervals are a t-test (+/- (t_{a/2})*s/sqrt(n)) and assume ...

Fsdb::Filter::dbmapreduce - reduce all input rows with the same key
Group input data by KeyField, then apply a function (the "reducer") to each group. The reduce function can be an external program given by ReduceCommand and ReduceArguments, or an Perl subroutine given in CodeFile or FilterCode. If a "--" appears bef...

Fsdb::Filter::dbmultistats - run dbcolstats over each group of inputs identified by some key
The input table is grouped by KeyField, then we compute a separate set of column statistics on ValueField for each group with a unique key. Assumptions and requirements are the same as dbmapreduce (this program is just a wrapper around that program):...

Fsdb::Filter::dbrvstatdiff - evaluate statistical differences between two random variables
Produce statistics on the difference of sets of random variables. If a hypothesized difference is given (with "-h"), to does a Student's t-test. Random variables are specified by: "m1c", "m2c" The column names of means of random variables. "sd1c", "s...
