Calculate confidence interval from a flat file.

bootci.py: calculate confidence interval from a flat file.

usage: bootci.py [options] <foo.flat>

where <foo.flat> is a file with parameters in columns and data sets
in rows. Such files are produced by flatfile.py and booma. The first
row should contain a column header listing parameter names. The second
should contain parameter estimates for the real data. Each succeeding
row should contain a parameter estimate for a bootstrap replicate.

Options may include:

  -c <x> or --conf <x>     Set confidence level.
  -h     or --help         Print this message.
  -l <x> or --label <x>    Set label.

The program writes to standard output.


# bootci.py run at: 2017-01-06 22:32:58.916983

Here, "par" lists the parameter names, "est" gives the estimates, and "low" and "high" give the lower and upper confidence bounds.

By default, the confidence level is 95%, but this can be changed with the –conf command-line option.

The –label <x> option will add a column in which every row contains the character string <x>. This is useful in data analysis, if one concatenates the output from several runs of bootci.py. The column of labels makes it possible to distinguish the estimates from different runs of bootci.py.

For example,

bootci.py --label lancre lancre.legofit boot*.legofit

would generate

# bootci.py run at: 2017-01-06 22:32:58.916983
# real data: lancre.legofit
# bootstrap replicates: boot0.legofit boot1.legofit boot10.legofit ...
# confidence: 0.950
