These include revised policy settings, recent statistical outturns and conjunctural indicators, combined with analyses based on specific economic and statistical models and analytical techniques, as outlined below. Assessing the current situation An important starting point in the forecasting process is the re-assessment of the economic climate in individual countries and the world economy as a whole.

Here, a combination of model-based analyses and statistical indicator models play an important role in "setting the scene" at the start of each projection round. A first step is to look at the range of relevant new information since the last projections were produced - such as changes in commodity prices in particular the oil priceexchange rates and interest rates, fiscal trends, the path of economic activity and other key variables — to see how the recent past has developed differently from what was previously expected.

Thus the likely impact of combined and individual changes in assumptions and new information on key aggregates can be assessed in consistent fashion for each of the major economies and economic groupings. The use of indicator models For the euro area and individual G7 economies, the near-term assessment also takes particular account of projections from a suite of statistical models using high frequency indicators to provide estimates of near-term quarterly GDP growth, typically for the current and next quarter or so.

These models typically combine information from both "soft" indicators, such as business sentiment and consumer surveys, and "hard" indicators, such as industrial production, retail sales, house prices etc.

The procedures are relatively automated and can be run whenever major monthly data are released, allowing up dating and choice of model according to the information set available. The most important gains from using the indicator approach are found to be for current-quarter forecasts made at or immediately after the start of the quarter in question, where estimated indicator models appear to outperform autoregressive time series models, both in terms of size of error and directional accuracy.

The main gains from using a monthly approach arise once one month of data is available for the quarter being forecast, typically two to three months before the publication of the first official outturn estimate for GDP.

For one-quarter-ahead projections, the performance of the estimated indicator models are only noticeably better than simpler time series models once one or two months of information become available for the quarter preceding that being forecast.

Forecasting with seasonal adjustment and linear exponential smoothing

Modest gains are nonetheless to be made in terms of directional accuracy from using the indicator models. Statistical indicator models are nonetheless limited in their ability to forecast quarterly GDP growth. Even with a complete set of monthly indicators for the quarter, the 70 per cent confidence bands around any point estimate for GDP growth in that quarter lie in the range from 0.

Forecasting errors can also arise for a variety of reasons, including revisions to the initial published data and inaccuracies in the projections of the incoming monthly data. Regular indicator model-based estimates of GDP now feed into both routine Economic Outlook assessment exercises and interim analyses and forecast updates released to the press on a routine basis.

While the OECD's world trade forecast is built as the aggregation of individual country import and export forecasts, additional tools are used to assess the short term evolution of world trade and its consistency with the GDP growth projection.

Firstly, indicator models to forecast world trade in the short term have been developed from the techniques used for short term forecasting of GDP growth to allow the incorporation of the most recent information from key monthly trade indicators.

These models are used routinely during forecasting rounds and also for interim analyses. To the extent that possible inconsistencies might be identified, this information is used iteratively in guiding the more detailed forecast components at country and regional levels.

The latter are typically constructed for each country using a set of variables that have been observed to be closely related to past turning points in a cyclical reference series such as GDP or, more typically, industrial production.

Making Critical Decisions. Effortless.

Key variables and relationships In making the overall assessment of current and future economic performance in individual countries, a number of key variables and relationships are examined, broadly along the following lines: Projections of private consumption and saving rates typically take into account real disposable income, household wealth, changes in the rate of inflation, monetary and financial conditions, and leading indicators of consumer confidence and retail sales.

Business fixed investment is mainly assessed in relation to non-financial sales, output and capacity utilisation and financial cash flow, monetary conditions and interest rates variables. Business sentiment and survey information is also taken into account. Projections for residential construction typically take account of demographic trends, housing stocks, real income and financial conditions, but also draw on cyclical indicators for the construction sector.

Projections of stockbuilding are usually made with reference to relevant stock-output and stock-sales ratios in relation to normal trends. Employment, wages and prices. Employment and other labour market trends are generally assessed on the basis of actual and projected activity.Combined forecasting methods can use regression methods, or a weighted average of a historical forecast and an advanced booking forecast, or a full information model.

Fildes and Ord () concluded from the research literature that. Sales forecasting and trends In order to safeguard from being caught unaware, business always tries to predict trends or patterns that will occur in the future. With historical data, a business is able to examine sales trends and thereby create a sales forecast. exponentially smoothed forecast and an estimated trend value exponentially smoothed forecast and a smoothed trend factor old forecast adjusted by a trend factor old forecast and a smoothed trend factor e.a moving average and a trend factor b (Time-series forecasting, moderate) - Forecasting Methodology Forecasting is an integral part in planning the financial future of any business and allows the company to consider probabilities of current and future trends using existing data and facts.

Financial forecasting is a very important activity in a company. It can determine the success or failure of the company. In performing the financial forecast, the company must analyze and interpret its market and its projected sales to arrive at a forecast.

In the initial stages of weather forecasting, for cyclonic development prediction much reliance was placed on the analysis of surface fronts. In those days, neither the exact relationship between the surface weather conditions and flow aloft was known, nor were the upper-air data available.
