Thefind_repeatsfunction identifies repeated values in an array and their counts, useful for spotting patterns or anomalies in discrete data. find_repeats.py #!/usr/bin/python from scipy import stats import numpy as np # Customer purchase counts in a week purchases = [1, 2, 3, 2, 4, 1,...
如果数据量过大的话,数据之间互相重叠,不容易看出单个x范围内数据的分布情况,这时我们可能要使用ECDF(empirical cumulative distribution function) ECDF: ECDF可以全景看到数据是如何分布的,类似于统计中的概率累积分布图。主要用于给定一个一维数组,咱们研究该数据的分布情况 def ecdf(data): """Compute ECDF for a ...
The mean value of a NumPy array is the average value of all the elements in the array. It is calculated by adding all elements in the array and then dividing the result by the total number of elements in the array. We use thenp.mean()function to calculate the mean value. For example...

Reinforcement learning is a general technique that allows an agent to learn an optimal policy and interact with an environment in sequential decision﹎aking problems. The goodness of a policy is measured by its value function starting from some initial state. The focus of this paper was to ...

For example, thettest_indfunction of SciPy returns only the T-value and the p-value. By contrast, thettestfunction of Pingouin returns the T-value, the p-value, the degrees of freedom, the effect size (Cohen's d), the 95% confidence intervals of the difference in means, the statistica...

SPSS SUM function returns the sum over a number of variables. In the presence of missing values, the sum over all valid values is returned. Keep in mind that the result may be somewhat misleading in this case.*The syntax below computes the within-subjects sum over our rating variables. ...
