Hierarchical axis labeling:pandas supports hierarchical indexing, allowing users to manage multi-level data structures within a single DataFrame. Time-series functionality:pandas includes multiple time-series a
Prepare Your Data📝: Your data should be in a pandas DataFrame format with columns representing the prompts, reference sentences, and outputs from various models. importpandasaspd# Example DataFramedata={"prompt": ["What is the capital of Portugal?"],"reference": ["The capital of Portugal is...
Linear Regression is a statistical technique used to model the relationship between a dependent variable and one or more independent variables. It fits a straight line to predict outcomes based on input data. Commonly used in trend analysis and forecasting, it helps in making data-driven decisions ...
nrows : pass number of rows we want in Grid to make subplots. width_ratios : set width ratio of subplot(adjust the width of plot). What is difference between axes and axis? Axis is a singular term, whereas,axes is a plural of axis. It does not have any other meaning; and whether ...
They can also be used to display data and trends over time when the bars are placed in order along an axis representing time. Scatter plot What it is: A scatter plot displays two variables of the same data point along an x and y axis. For example, a point on a scatter plot could ...
Series are 1D arrays with axis labels. NumPy uses arrays and matrices, which are n-dimensional and homogeneous in data type. Handling of Data Types Pandas can handle a mix of different data types (e.g., integers, strings, floats) in a single DataFrame. NumPy is more efficient with ...
What is a regression line? A regression line is a straight line used in linear regression to indicate a linear relationship between one independent variable (on the x-axis) and one dependent variable (on the y-axis). Regression lines may be used to predict the value of Y for a given val...

Chapter 1, Pandas Foundations, covers the anatomy and vocabulary used to identify the components of the two main pandas data structures, the Series and the DataFrame. Each column must have exactly one type of data, and each of these data types is covered. You will learn how to unleash the...
In a boxplot graph, the box represents the data’s interquartile range (IQR), which is the 50 percent of data points above the first quartile and below the third quartile. Each whisker (line) on the side of a boxplot represents the top and bottom 25 percent of data points, where the...
