In linear regression,dataare modelled using linear functions, and unknown modelparametersareestimatedfrom the data. Such models are calledlinear models. Single variable linear regressionYear = x where x = 1, 2, 3,...., 10Demand = yD = y + e Where D is actual demande= D yTo find out whether this is the line of best fitted to be sure that this sum of squares is a min.Determination of the regression lineIn general formy = a + bxWhere y is dependent variable, and x is independent data variable.When a and b specified this line will be specified.So the company which we took is Infosys and we have identified for major markets in which the demand could be forecasted.
