It is inherited from the of generic methods as an … WebFor example, to model IQ data, you'd build iq = scipy.stats.norm (loc=100, scale=15) because IQs are constructed so as to have a mean of 100 and a standard deviation of 15. Why don't we just call them mean and sd? It helps to have a more generalized concept because not every distribution has a mean (e.g., the Cauchy distribution). malla finanzas utpl https://sarahnicolehanson.com
