Another common use of regression analysis in finance is in forecasting financial statements. Multiple regression analysis might be more suited to determine the impact that changes in model drivers will have on revenue and expenses. Simple linear and multiple linear regression analyses are the most used variations. In contrast, nonlinear regression is used for what if analysis vs sensitivity analysis complex data where the independent and dependent variables demonstrate a nonlinear relationship. The two main types of sensitivity analysis are local sensitivity analysis and global sensitivity analysis. Based on 100 transactions today, a 10%, 50%, or 100% increase in customer traffic equates to an increase in transactions by 5%, 25%, or 50% respectively.
The results were robust to various statistical models, but showed more variability in the presence of a larger cluster effect (higher within-patient correlation). In this section, we describe scenarios that may require sensitivity analyses, and how one could use sensitivity analyses to assess the robustness of the statistical analyses or findings of RCTs. These are not meant to be exhaustive, but rather to illustrate common situations where sensitivity analyses might be useful to consider (Table 2). In each case, we provide examples of actual studies where sensitivity analyses were performed, and the implications of these sensitivity analyses. In contrast, scenario analysis requires one to list the whole set of variables and then change the value of each input for different scenarios. For example, the best-case scenario can help one predict the outcome when there’s a decrease in interest rates, an increase in the number of customers, and favorable exchange rates.
Sensitivity analysis allows you to check your work, helping you see whether or not the key drivers you modeled around are actually most impactful to outputs. That’s why the most important part of scenario planning and analysis isn’t about your model — it’s about understanding which levers you should pull to build out the “what-ifs” of your forecasting process. In some cases this procedure will be repeated, for example in high-dimensional problems where the user has to screen out unimportant variables before performing a full sensitivity analysis. I have proposed a form of organized sensitivity analysis that I call ‘global sensitivity analysis’ in which a neighborhood of alternative assumptions is selected and the corresponding interval of inferences is identified. Conclusions are judged to be sturdy only if the neighborhood of assumptions is wide enough to be credible and the corresponding interval of inferences is narrow enough to be useful. Even though both analyses work similarly by altering inputs, they have different purposes and workings.
He observes that total revenue from that item depends on the price and volume sold. This process is repeated to obtain the measure of sensitivity for each input while keeping all the other inputs the same. A higher measure of sensitivity for an input implies that the output is more sensitive to changes in that input.

A Financial Sensitivity Analysis, also known as a What-If analysis or a What-If simulation exercise, is most commonly used by financial analysts to predict the outcome of a specific action when performed under certain conditions. A financial model is a great way to assess the performance of a business on both a historical and projected basis. The fields you want to measure the consequences of changing are the target variables.
Patients or elements within a cluster often have some appreciable degree of homogeneity as compared to patients between clusters. In other words, members of the same cluster are more likely to be similar to each other than they are to members of another cluster, and this similarity may then be reflected in the similarity or correlation measure, on the outcome of interest. An outlier is an observation that is numerically distant from the rest of the data. The problem with outliers is that they can deflate or inflate the mean of a sample and therefore influence any estimates of treatment effect or association that are derived from the mean. To assess the potential impact of outliers, one would first assess whether or not any observations meet the definition of an outlier—using either a boxplot or z-scores[16].
Investigators need to identify any key assumptions, variations, or methods that may impact or influence the findings, and plan to conduct some sensitivity analyses as part of their analytic strategy. The final report must include the documentation of the planned or posthoc sensitivity analyses, rationale, corresponding results and a discussion of their consequences or repercussions on the overall findings. When a company wants to determine different potential outcomes for a given project, it may consider performing a scenario analysis.
