Fisher matrices are used frequently in the analysis of combining cosmological constraints from various data sets. They encode the Gaussian uncertainties of multiple variables. They are simple to use, and I show how to get up and running with them quickly. Python software is also provided. I cover how to obtain confidence ellipses, add datasets, apply priors, marginalize, transform variables, and even calculate your own Fisher matrices. This treatment is not new, but I aim to provide a clear and… CONTINUE READING
