To calculate the standard deviation, lets first calculate the mean of the list of values. Standard Deviation. As our primary concern is about making plots more beautiful, the explanation of code about the mathematical aspects will be rather brief. Hence Monte Carlo integration gnereally beats numerical intergration for moderate- and high-dimensional integration since numerical integration (quadrature) converges as \(\mathcal{0}(n^{d})\).Even for low dimensional problems, Monte Carlo Since the normal distribution is a continuous distribution, the shaded area of the curve represents the probability that X is less or equal than x. From the small code experiment on the MNIST dataset, we obtain a loss and accuracy graph for each activation function How a normal distribution looks with a mean $\mu$ of zero and a standard deviation $\sigma$ of one.

Step 2: Import the CSV File into Python. Then we ran it through the norm.pdf() function with a mean of 0.0 and a standard deviation of 1, which returned the likelihood of that observation. Since we are computing the mean and standard deviation from a single batch as opposed to computing it from the entire data. Here are some hints: 1) convert your dates to datetime, if you haven't already 2) group by year and take the mean 3) take the standard deviation of that. You can store the values as a numpy array or a pandas series and then use the simple one-line implementations for calculating standard deviations from these libraries.
