examine-ev man page

USAGE:

        examine-ev [options] <evs-file>

PURPOSE:

       Without graphics, examine the variance-covariance (VCV) of the generalized-inverse problem.
      Can also calculate the slope-bias and its uncertainty, i.e. the sum
s=∑iβipis=∑_i β_i p_i
         δs=Δσ2β⊤⋅C⋅β\delta s = \sqrt{\Delta\;\sigma^2\;\beta^\top\cdot C \cdot \beta}

      where  C  is the inverse of the VCV and

           Δ:Γ(ν/2,Δ/2)Γ(ν/2)=1-p\Delta: \; \frac{\Gamma(\nu/2,\;\Delta/2)}{\Gamma(\nu/2)}=1-p

      The program in fact studies C.

OPTIONS:
    
  -V                 - print the VCV and a little more

  -p <index-ranges>  - selects the columns of the VCV matrix
                       Specify single indexes and ranges like
                       i1,i2,i3-i4     etc.

  -b <coeff-file>    - read the β\beta-array from this file


The beta file:
In the case of slope-biases, you can use a script that extracts the data
from the urtap log-file:
    extract-slope-bias logs/urtap-openend-fspl-ochy.log >! tmp/all-slope-biases.dat

EXAMPLE:
         examine-ev -p 99-109 -b tmp/all-slope-biases.dat tt/urtap-090615-OPNEND-ochy.evs
