It can be seen that we are four times faster than scipy cdist, five times faster than xarray.corr, 60 times faster than forloop, 110 times faster than xr.apply_func and 200 times faster than numpy.corrcoef. Moreover, xarray and numpy can not return thep value. We can simply check the...

Making informative visualizations (sometimes calledplots) is one of the most important tasks in data analysis. It may be a part of the exploratory process—for example, to help identify outliers or needed data transformations, or as a way of generating ideas for models. For others, building an...
• NumPy is implemented in C and optimized for numerical computations • Supports various mathematical functions such as trigonometric, exponential, log, etc. • Deals with complex numerical computations like statistical analysis, Fourier transforms, etc. ...
This tutorial will introduce the use of Python for statistical data analysis, using data stored as Pandas DataFrame objects. Much of the work involved in analyzing data resides in importing, cleaning and transforming data in preparation for analysis. Therefore, the first half of the course is comp...
