Some have an inverse CDF. There’s a general pattern to function names, but there are exceptions. Probability function names in Excel typically consist of a base name and a suffix. The base name is an abbreviation of the distribution name. The suffix is either DIST or INV. SpletThe norm function has a very handy isf function that does exactly this: cdf_value = np.sort (np.random.rand (npts_sample)) cdf_inv = norm.isf (1 - cdf_value) Does such a function exist for kde_gaussian? Or is it straightforward to construct such a function from the already implemented methods? python numpy scipy scientific-computing Share Follow steve baugh obituary
