1 In moving average method, we cannot find the trend values of some: Middle periods End periods Starting periods Between extreme periods
2 For a least squares linear trend Y = a + bx, the Σ(Y - Y)2 = 0 when: All the Y-values are positive All the Y-values lie on the line All the Y-values lie above the line None of these
3 The additive model of the time series is: Y = T + S + C + I TSCI Y = a + bX Y = a + bX + cX<sup>2</sup>
4 The trend values in freehand curve method are obtained by: Equation of straight line Second degree parabola Signal Graph
5 The multiplicative time series model is: Y = T + S + C + I TSCI Y = a + bX Y = a + bX + cX<sup>2</sup>
6 The rise and fall of a time series periods longer than one- year is called. Secular trend Seasonal variation Cyclical variation Irregular variation
