BREAKDOWN OF PRIMARY RESPONDENTS
FORECASTING TECHNIQUES
We at Wantstats follow an extensive process for arriving at market estimations, which involves the use of multiple forecasting techniques, as mentioned below.
Forecasting Techniques
Description
Qualitative and Quantitative Analysis
A combination of qualitative approach, i.e., primary interviews with industry experts to understand the interviewees’ opinions and judgments, more commonly known as the Delphi method, and quantitative analysis to forecast future data based on historical and current data.
Weighted Average Approach
Via this approach, future data is calculated based on the mean of the past data under the assumption that some factors affecting the market in the past will continue to have a similar impact in the future.
Drift Method
This approach is used to vary the forecast, which increases or decreases in market factor over time, depending on various parameters affecting the change in the trends of the market.
Time Series Methods
The integration of several time series methods such as moving average, moving weighted average, linear prediction, and trend estimation is applied while determining the year-on-year growth rate and the compound annual growth rate of the market being studied.
Causal/Econometric Forecasting Methods
Various economic factors such as inflation rate, fiscal policies, changes in government regulations, taxes, labor costs, and interest rates are taken into consideration while determining the current market size and predicting the future market growth rate.
Judgmental Methods
This involves the collection of intuitive judgment, opinions, and probability estimates from industry experts in the case of new or upcoming markets/technologies for which no prior data is available.
Regression Analysis
This type of statistical modeling is carried out for predicting and forecasting dependent and independent variables that will directly or indirectly impact the market.
Probabilistic Forecasting
This forecasting method is carried out to assign a probability to every possible outcome ranging from the least optimistic to highly optimistic, which helps in gauging the market under stable conditions.
PESTLE Analysis
Political, economic, social, technological, legal, and environmental factors are taken into consideration while deriving the fluctuations in the growth rate of the market.
Porter’s Five Forces Analysis
By understanding the supplier-side and demand-side factors, the current market scenario can be estimated, and future market scenarios predicted, which aid in deriving the growth rate of the market.
RESEARCH METHODOLOGY FOR MARKET SIZE ESTIMATION
Understanding and penetrating the market in terms of valuation is a crucial task in the process of business research. This again becomes significantly important while investing and choosing business opportunities. In this regard, we at Wantstats performs two ways market sizing approach simultaneously, namely top-down and bottom-up approaches. In this step, we place different data points, numeric attributes, information, and industry trends at an appropriate space to deduce the estimates & forecast values over the coming years. We use different mathematical models to estimate the market sizes of different economies and segments. Each of which is further summed up to define the total market.
We at Wantstats own a proprietary statistical tool for market estimations, which helps us to comprehend market size estimates & forecasts for different markets and industries.
bottom-up and top-down approaches
Wantstats Analysis Overview
BOTTOM-UP APPROACH
In the bottom-up approach, the revenue of key companies and their shares in the market are assessed to deduce the market size. More than 20 key players operating in the global bariatric surgery devices market are studied. The segmental revenue of each player is analyzed, and the size for the global bariatric surgery devices market is extracted from the segmental/product/service revenue with the help of secondary and primary research. The extracted size for the market is then validated with industry experts and partner consultants. This derived market size contributes to around 65% to 70% of the total global market share in terms of revenue for the bariatric surgery devices market. Using the data triangulation method, the overall global market size is estimated.
The overall market size is then used in the top-down procedure to estimate the size of the other sub-markets with the help of percentage splits of the market segments from secondary and primary research. The demand-side analysis is conducted, in which the expenditure of significant industry players in each region is studied. The end-users considered in the scope of this research study contributes around 70% of the total spent in the bariatric surgery devices market.
The countries considered in the scope of the bariatric surgery devices market are the US, Canada, the UK, Germany, France, Italy, Spain, China, Japan, South Korea, India, Singapore, Malaysia, Indonesia, South Africa, and others.
The figure below depicts the process of market estimation using independent tools employed by our analysts to arrive at the sizing of the market.
Wantstats Analysis Overview
As a part of the market engineering, both top-down and bottom-up approaches are utilized along with data triangulation models to derive and verify the market sizes and forecast over the coming years.
DATA TRIANGULATION
After arriving at the overall market sizes, the total market is divided into several segments and sub-segments. Again, the market breakdown and data triangulation procedures are implemented, wherever applicable, to complete the overall market engineering process and gather the exact statistics for all segments and sub-segments. The data is triangulated by studying various factors and trends from the demand and supply sides. Along with this, the market size is validated using the top-down and bottom-up approaches.
VALIDATION
Validation is the most crucial stage of the report making the process. Validation via an intricately designed feedback process helps us finalize the sizing estimates and forecast for the final collation. Extensive primary research is performed to verify the information. This includes telephonic and personal interviews, e-mails, feedback forms, questionnaires, and polling options/answers with a group of relevant industry participants. Validation helps to duly check the authenticity of the key industry trends, market dynamics, company market share, different business models, and conclusions.
