best while recognized models are used together. There are various types of forecasting methods such as: Qualitative study‚ Time series analysis‚ Causal method etc. For this particular assignment‚ we have used some methods of Time series analysis like Simple Moving Average‚ Single Exponential Smoothing‚ and Regression Analysis etc. Various models‚ mostly quantitative time series models have been used to determine the forecasted future monthly sales quantity of Laptops for the month of November 2013

alternatives. To build this model‚ we gathered the oil prices to analyze the impact of the changes in these prices on the changes in natural gas prices. The results of the forecasting exercise‚ carried out using the US Natural Gas 3 Months Strips series‚ suggest that the forecasting approach can be used to obtain a performance measure for the price.

and consumption series of India covering the period of 1980-2009. Data about certain indicators were obtained from the official web site of World Bank. In first step of data analysis appropriate ARMA model was determined using correlogram and information criteria as well‚ and applied to the consumption data only. These models (ARMA and ARIMA models) are built up from the white noise process. We use the estimated autocorrelation and partial autocorrelation functions of the series to help us select

returns in India. The study by taking into consideration the domestic gold prices and stock market returns based on BSE 100 index‚ investigates the Granger causality in the Vector Error Correction Model for the period January 1991 to December 2009. The analysis provides the evidence of feedback causality between the variables. It infers that the Gold prices Granger-causes stock market returns and stock market returns also Granger-causes the gold prices in India during the sample period. Thus‚ both the variables
