Lab 3: Model Building I: Linear models
Start Jan 29 –- Due Feb 3
Goals
In this lab, students will learn to:
Build a statistical model from a astrophysical model and measurement process.
Fit a linear model to data using multipe techniques:
Linear Algebra
Linear Modeling Package
Probabilisitic Programming Language
Visualize the loss function surface for linear models
Characterize the sensitivity of results to the choice of prior
Critically evaluate the uncertainties in model parameters.
Students will strengthen their astronomical knowledge by:
Measuring Hubble constant from observations of supernovae
Detecting transit timing variations for a transiting exoplanet
Instructions
Work through the ex1.jl and ex2.jl (Pluto notebooks) and save updates in your personal repository.
Once the instrctor and/or TA has provided feedback, review the feedback
