The callable can be any function, method, or object with .__call__() that accepts two one-dimensional arrays and returns a floating-point number. Linear Correlation Linear correlation measures the proximity of the mathematical relationship between variables or dataset features to a linear function....
chapter1 Matplotlib line plot: 更适合时间序列 scatter plot When you have a time scale along the horizontal axis, the line plot is your friend. But in many other cases, when you're trying to assess if there's a correlation between two variables, for example, the scatter plot is the bette...
Python implementation of the Mantel test (Mantel, 1967), which is a significance test of the correlation between two distance matrices. Installation The mantel package can be installed using pip: pip install mantel Usage mantel provides one function, test(), which takes the following arguments: X...
Let's visualize the data that you loaded above using a scatterplot to find out how much one variable is affected by the other variable or let's say how much correlation is between the two variables. You will use matplotlib library to visualize the data using a scatterplot. import matplotlib...

broadcasting. Broadcasting is a way of performing implicit operations between two arrays. It allows you to perform operations on arrays ofcompatibleshapes, to create arrays bigger than either of the starting ones. For example, we can compute theouter productof two vectors by reshaping them ...
