Explain the descriptive statistics and draw scatter plots

Reference no: EM13113627

Explore the descriptive statistics and draw some scatter plots. Does this meet the basic assumptions of regression?

Run a multiple regression using the variables. Analyze results and explain t-statistics, coefficients and r-square.

How successful is the regression? How much variance of the Demand was explained?

Is there any way to improve the regression? Any "missing" information? How do you obtain it and how would you use it? Is the extra information really necessary?

You are also welcome to explore time-series. Does it help at all?
