5.8 LAB: Structuring data using mutate()The hmeq_small dataset contains information on 5960 home equity loans, including 7 features on the characteristics of the loan.• Load the hmeq_small.csv data set as a data frame.• Create a new data frame with the columns LOAN and VALUE standardized and saved as LOAN STAND and VALUE_STAND.• Create a second data frame with the columns LOAN and VALUE normalized and saved as LOAN_NORM and VALUE_NORM.• Print the summaries of the new data frames.Ex: Using the first 100 rows, found in hmeq_sample.csv, the output is:

We start by importing the necessary libraries: pandas for data manipulation and numpy for numerical…

All geographic data-sets will have a coordinate system. that is used throughout ArcGIS to display, measure, and transform geographic data. If the coordinate system for a data-set is unknown or incorrect, you can use a specific tool to specify the correct coordinate system as you did this in this lab. You must know the correct coordinate system of the data-set before using this tool. The tool in ArcGIS Pro is called "Project" True False
TODO 12 Let's now split our input data X and labels y into a train and test set using the train_test_split() function (docs). Here we'll use the 80-20 split rule where we use 80% of the data for training and 20% for testing. Lastly, we'll seed our split using the random_state keyword argument which will make sure we create the same split every time we run the function. Use the train_test_split() function to get a train and test split. Store the output into X_train, X_test, y_train, and y_test. Pass the required arguments X and y. Further specify we want to use 20% of the training data by setting the test_size keyword argument. Lastly, pass the keyword argument random_state=42 to set the random seed so we get the same split every time we run this code. Print the shape for X_train. Print the shape for y_train. Print the shape for X_test. Print the shape for y_test. # TODO 12.1X_train, X_test, y_train, y_test = todo_check([ (X_train.shape == (413, 29), 'X_train does not have the…
We will use built in datasets to practice making plots in R. You need to save all plots and upload with your script. 1. We will use mtcars. So first define x as the wt column of mtcars and y as the mpg column of mtcars. a. How do you find out more about the mtcars, dataset? Provide a synopsis b. Make a plot using plot() and be sure to give it a main and axes title c. Change point shape to 19 using the pch parameter for the plot function and remove the frame
