Linear Regression with 1 regressor (CHAPTER 4) Aim: estimate the causal effect on Y of a unit change in X Slope: expected change on Y for a unit change in X E[X|Y] = b0 + b1X Method: minimize the sum of square errors or average squared difference between actual Yi and predicted Yi‚ min u (OLS)‚ u = error which contains omitted factors that influence Y that is not captured in X and also error in measurement in Y b0 and b1 are population parameter‚ the hats are the estimates‚ we pick the hats so

eigenvalue is 1 (one). Eigenvalues are introduced in the context of linear algebra or matrix theory. The introduction and development of the notation of matrix and system of linear algebra followed the development of determinant‚ which rose from the study of coefficient system of linear equations. Leibnitz‚ one of the founders of calculus used determinant in 1693 an Cramer presented his determinant - based formula system of solving linear equations (known as Cramer’s’ rule) in 1750. In 1848‚ James J

(b) A toy company manufactures two types of dolls‚ a basic version doll- A and a deluxe version doll-B. Each doll of type B takes twice as long to produce as one of type A‚ and the company would have time to make maximum of 1000 per day. The supply of plastic is sufficient to produce 1000 dolls per day (both A & B combined). The deluxe version requires

two currencies has been changed during the crisis‚ we separately discuss three time series periods: * 1999 2013 * 1999 to 2008 * 2008 to 2013. -------------------------------- Autoregressive time series A key feature of the log-linear model’s depiction of time series and a key feature of the time series in general is that current-period values are related to previous period values. For example current exchange rate of USD/EUR is related to its exchange rate in the previous period

Strike rate (in case of a batsman) to physical attributes of players such as age. We applied techniques of multiple linear regression to determine such factors which were deterministic in pricing the players. Best Regression model(s) The following are the independent variables which are derived after doing regression analysis.

performance of the system. Techniques and tools of operation research: Linear programming: You can use linear programming to find a solution for optimising a given objective. The objective may be to maximize profit or to minimize cost. Inventory control methods: The production‚ purchasing‚ and material managers are always confronted with questions‚ such as when To buy‚ and how much to keep in stock. Goal programming: In linear programming ‚ you take a single objective function and consider all other
