It is natural to try to find the best line that fits the data points. If we can find this line, then we can use it to make all sorts of other predictions. In this project, we're going to use several functions to find this line using a technique called least squares regression. The result will be what we call the least squares regression line (or LSRL for short). In order to do this, you'll need to program a statistical computation called the correlation coefficient, denoted by r in statistical symbols: NOTE: Equation is written assuming you start at the value 1. Lists start at index 0. Once you have the correlation coefficient, you use it along with the sample means and sample standard deviations of the x and y-coordinates to compute the slope and y-intercept of your regression line via these formulas: Tasks: In this project, you must read…

Please continue from the given code:
- MatLab Load the data flu.mat (you can do this by typing load flu in your script). This data is the flu trends seen in the United States 2005-2006, divided by region. We will use regressions to look at the data during flu season in the Pacific region. Create your x data: have x equal to 1:30. These represent 30 weeks between Oct. 2005 and May 2006. Create your y data: have y equal to flu.Pac(1:30)’. This is the flu trend for each week. Make sure you have an apostrophe after the last parenthesis. Fit the data below with a straight line and with a 2nd order polynomial. Use least-squares regression. Calculate the coefficient of determination (r^2) and the correlation coefficient (r) for each regression. Plot the two regression curves against the data. Which regression is better? Is there a polynomial you think would work better? Describe the data – what does it mean to you?I only need to use numpy library for this project I am not allowed any external library except panda and numpy. and work should be done in Jupyter notebook This project asks you to implement a logistic regression classifier, and apply it on a realdata set.We use the Breast Cancer Wisconsin dataset from UCI machine learning repository:http://archive.ics.uci.edu/ml/datasets/Breast+Cancer+Wisconsin+%28Diagnostic%29Data File: breast-cancer-wisconsin.data (class: 2 for benign, 4 for malignant)Data Metafile: breast-cancer-wisconsin.names we have seen that logistic regression is a convex problem, and gradientdescent gives the optimal parameters. However, the efficiency is highly dependent onthe step length which is left for users to tune. In this assignment, we look at a fastersolution called Newton’s method (a.k.a. Newton-Raphson method), which avoids theuse of step length.
