Consider the following function that calculates the variance of a sample of numeric data:Python >>> def variance(data, ddof=0): ... mean = sum(data) / len(data) ... return sum((x - mean) ** 2 for x in data) / (len(data) - ddof) ... >>> variance([3, 4, 7, 5,...
That’s how you can obtain the statistics for a single column. Sometimes, you might want to use a DataFrame as a NumPy array and apply some function to it. It’s possible to get all data from a DataFrame with .values or .to_numpy(): Python >>> df.values array([[ 1, 1, 1]...
The function that calculates this estimator is below. def Maximum_Likelihood(param, pmf): # probability mass function, param - parameter for which I want to get estimator i = symbols('i', positive=True) n = symbols('n', positive=True) Likelihood_function = Product(pmf, (i, 1, n)) ...
