HELP!! In Matlab The scenario is simple: A set of (x,y) data is available in the form of a simple text file – the first column represents x-values and the second column represents y-values. The task at hand is to provide the best model (or curve fit) to this set of data. Your application should provide the means to fit the following curve types to the data: Linear (first order polynomial) of form (?? = ???? + ??) with non-zero...

MATLAB code please
Obtain a temperature data of Reno from September 2016. Find the data for a typical sunny day, between 6am to 6pm. Write a MATLAB code that uses linear least squares to fit the data. Then, obtain the same temperature data from the same day in year 2017. Plot the data points and the regression line on the same graph. Does the least-squares line fit the data from 2017? Why or why not? Discuss your result.

Suppose that the data (X1, Y), ... (Xn, Yn is generated by the following ("true") model: a+ bX; + сX; +ei, where a, b, c are some parameters and ei are independent errors with zero mean and variance a2. Suppose that we fit the simple linear regression model to the data (i.e. we ignore the quadratic term cX2) using the OLS method. Find the expectation of the residual from the fit.
