Method decision tree for parameter estimation and model comparison

Method decision tree

  • Write down your problem mathematically/statistically; stripping out astronomy-specific details from your model (e.g. pre-compute redshifts, weights, etc.)
  • Ideally, shorten and simplify it down to primitives of math and statistics, which can be implemented in any language.

For the following decision tree, keep in mind that typically, one first thinks

  • I just want to quickly find the best fit on this.

Progress bar for rsync
========================
Shows file progress and total progress as a progress bar.
Usage
---------
Run rsync with -P and pipe into this program. Example::

rsync loop that updates remote directory when local directory changes (using inotify)
while true
do

Draw random numbers from broken powerlaw (broken code ATM)
import numpy
# Sampling from a broken powerlaw or powerlaw segments
# Reference material:
# http://mathworld.wolfram.com/RandomNumber.html
# The strategy is to draw from each powerlaw segment, and make sure the proportions are right based on the segment integrals
# This code does not work correctly, improvements are welcome

Arxiv submission tool
# To submit just at the right time (deadline 14:00 EST),
#
# How to use:
# - Make sure your clock is synced to https://arxiv.org/localtime
# - Prepare arxiv submission up to last page, move cursor over submission button
# - execute below function which will produce a left-button mouse click at 14:00
# - if too early, unsubmit, fix clock, try again the next day
#
# Hopefully one day arxiv will randomize their submission ordering.
