Write this photo in Matlab use: c. In the main script files, plot the CDF of SNR for all users and discuss the results. The following is an example of CDF graph. Make sure to plot the SNR in dB. CDF is a cumulative distribution function that present the probability the data has <= certain level. IN the figure below for example, the probability the SNR <=500 is 0.5. The Y axis here represent the probability, while the X axis is the SNR data. 09 07 05 04 03 02 01 500 1000 1500 2000 2500 3000 3500 4000 4500 SNR NS P 0

Analysts at a start-up company are analyzing 35 months of sales data. They partition the data (the first 20 observations are assigned to the training set; the most recent 15 months are in the test set). The only independent variable is T (month number, ranging from 1 to 35). Five models (polynomials of order 1 - 5) are fit to the data. The first order is just the linear model; the 2nd order polynomial is the quadratic model; order 3 is the cubic model, etc. In each case the model is fit on the training data, and scored on both the training and test data sets. The results are below. Based on this output, which is the best predictive model?
