I am new to Python, albeit not to programming, and I've found on a tutorial this Python implementation of a simple linear regression algorithm. So far I've only written the code for plotting the graph, with no linear regression. However, as I try to run the code into the Python command prompt, I only get an empty plot. I've tried to correct possible errors with the tutorial and other resources on the net, though I wasn't able to find anything. Could somebody help me figure this out? (PS. I am new to Stack Overflow ) This is the code: import numpy as np import pandas as pd import matplotlib.pyplot as plt data = {'Years of Experience':[ 1.1, 1.3, 1.5, 2. , 2.2, .29, 3. , 3.2, 3.2, 3.7, 3.7, 3.9, 4. , 4. , 4.1, 4.5, 4.9, 5.1, 5.3, 5.9, 6. , 6.8, 7.1, 7.9, 8.2, 8.7, 9. , 9.5, 9.6, 10.3, 10.5], 'Salary':[ 39343., 46205., 37731., 43525., 39891., 56642., 60150., 54445., 64445., 57189., 63218., 55794., 56957., 57081., 61111., 67938., 66029., 83088., 81363., 93940., 91738., 98273., 1011302., 113812., 109431., 105582., 116969., 112635., 122391., 121872.]} dataframe = pd.DataFrame(data) dataframe.head() x = dataframe.iloc[:,0].values.reshape(-1,1) y = dataframe.iloc[:,1].values.reshape(-1,1) plt.scatter(x,y) plt.title("Years of Experience vs Salary") plt.xlabel("Years of Experience") plt.ylabel("Salary") plt.show() Continue reading...
