cosmicfish_pylib.fisher_operations.marginalise_over

cosmicfish_pylib.fisher_operations.marginalise_over(fisher_matrix, names)

This function marginalises a Fisher matrix over the parameters in names. The new Fisher matrix will not have the parameters specified in names. The calculation is performed in the numerically stable way.

Parameters:

• fisher_matrix (cosmicfish_pylib.fisher_matrix.fisher_matrix) – input Fisher matrix
• names (list of string) – list of names of the parameters over which the Fisher will be marginalised.

Returns:

A Fisher matrix with the names parameters marginalized.

Return type:

cosmicfish_pylib.fisher_matrix.fisher_matrix
