Explanation:
NumPy (Numerical Python) is a powerful library in Python that provides support for large, multi-dimensional arrays and matrices, along with a collection of mathematical functions to operate on these arrays efficiently. NumPy is often used for numerical computations and data manipulation tasks.
Explanation:
An autocorrelation plot is a plot that helps check randomness in a time series. It is commonly used to identify patterns or dependencies in the data over different lags (time intervals).
Explanation:
The plot that can help check the randomness of a time series or a data set is called an "autocorrelation plot" or "ACF plot." The ACF plot displays the autocorrelation coefficients on the y-axis, while the lag (time interval) between observations is shown on the x-axis.
Explanation:
The base layer for all sparse indexed data structures is typically an array or a similar data structure that provides a contiguous block of memory. In the case of sparse indexed data structures, this base layer is often referred to as a "sparse array" or a "sparse matrix."
Explanation:
All of these can be used as data in Pandas.
Pandas provide various data structures, such as Series and DataFrame, that can hold and manipulate data. These data structures can be initialized with different types of data.
Explanation:
The statement "import pandas as pd" is a valid way to import the Pandas library in Python. It is a common convention to import Pandas using the alias "pd" to make it easier to refer to the library when using its functions and classes throughout the code.
