What's a Mine-der?
A Mine-der is StarMine's way of highlighting potential issues with estimates. Mine-ders are not necessarily negative; they are simply a way of flagging potential data issues. Mine-ders that appear on the Current Data pages are triggered in at least one of the following ways:

1. An estimate is older than the most recent RevisionCluster
   
2. An estimate is greater than two standard deviations away from the mean
   
3. An estimate is at least 100 days old and at least U.S. $0.02 away from the mean
   
4. An estimate has been excluded from the mean by Refinitiv
   
   

In addition to displaying Mine-ders in StarMine Monitor, StarMine also alerts users by e-mail when Mine-ders are triggered, if the user has chosen to receive such notifications. Other Mine-ders that are sent via e-mail are for estimates or recommendations that have been stopped or picked up by another analyst, or estimates whose primary basis has changed. What do I do to start or stop receiving Mine-der alerts by E-mail?

How are they used?
"Cluster" is short for a cluster of analyst revisions, or the occurrence of a significant number of analysts revising their estimates in a short time period. This often occurs during the release of company news, changes in the industry, earnings releases, and other issues that affect future earnings. We systematically detect RevisionClusters and then use the Cluster's begin date as a filter. Those analysts who have not revised their estimate are then notified there is potentially material company-related news, which could affect company performance. This also helps StarMine's Buy Side clients know which estimates have been updated since the recent news. How can I identify a cluster on the current data charts?
Clusters are visually identified on charts with a vertical purple line. There is a purple asterisk to the right of the chart with text that identifies the date of the cluster and the number of analysts that revised since the beginning of the cluster. Why do some Mine-ders get triggered significantly later than expected?
We download daily revisions and updates of analysts' estimates from our data vendors. To ensure data accuracy, we also check our historical data against a CD provided by our data vendors on a monthly basis. We additionally run weekly checks of our data against that of our vendors for further accuracy verification. In doing so, we sometimes receive data that should have triggered a Mine-der on a previous date. What is SD, or Standard Deviation?
Standard Deviation (SD) indicates how tightly all the various estimates are clustered around the mean during the fiscal year or fiscal quarter. This is important because it can highlight "outlier" estimates, which might have been made in error or inputted incorrectly into I/B/E/S. The literal definition of Standard Deviation is a statistic used as a measure of the dispersion in a distribution, equal to the square root of the arithmetic mean of the squares of the deviations from the arithmetic mean. What are the possible reasons Refinitiv would exclude my estimate?

• Different Basis: StarMine tracks and scores one basis per fiscal period per stock; e.g., EPS, EBG, FFO. Your estimate was filed in the Refinitiv database on this basis and Refinitiv decided it didn't conform to the exact basis definition used by the other analysts contributing to this stock's consensus, and therefore excluded it.
  
  
• Single Basis: Some analysts publish an estimate on one basis only, and some publish on multiple bases but their firm's data feed only communicates one basis. Separately, StarMine chooses one basis according to whichever basis is published by the most analysts for each stock, and uses that basis alone. If the analyst's bases do not include the basis StarMine has chosen, StarMine will not use the analyst's estimate. In some cases, where an analyst's estimate based on StarMine's chosen basis is not available, Refinitiv will copy over an estimate from another basis and then exclude it, so that users can see that Refinitiv has the data from this broker but not on this basis.
  
  
• Out of date: Refinitiv reviewed your estimate and decided that it was out of date; e.g., it did not incorporate material news since it went into effect.
  
  

If Refinitiv has incorrectly excluded your estimate and you wish a correction to be made, go to How do I report errors? What are the possible reasons my estimate would be stopped?

• You stopped it: You or your firm may have stopped an estimate, or accidentally deleted it, in which case it would appear never to have existed.
  
  
• Refinitiv stopped it: They may have stopped an estimate based on information received from you, or they may have accidentally deleted it, in which case it would appear never to have existed.
  
  
• It appears to have been stopped, but was actually excluded: If Refinitiv excludes an estimate, the exclusion will appear as a stop. Refinitiv does not indicate to StarMine whether the estimate was excluded or stopped.
  
  

If your estimate was stopped incorrectly and you wish a correction to be made, go to How do I report errors? Why might my estimate have been moved to another analyst?

• You moved it: You or your firm may have simply transferred responsibility for the stock to another analyst.
  
  
• Shared coverage is not being assigned correctly: Sometimes Refinitiv will misinterpret the information the analyst's firm provides when more than one analyst cover a stock and make recommendations jointly.
  
  

If your estimate was moved to another analyst incorrectly and you wish a correction to be made, go to How do I report errors? What are the possible reasons my recommendation would be stopped?

• You stopped it: You or your firm may have stopped the recommendation or accidentally deleted it.
  
  
• Refinitiv stopped it: They may have stopped a recommendation based on information received from you, or they may have accidentally deleted it, in which case it would appear never to have existed. For example, if you have no estimates on a stock, Refinitiv may stop your recommendation.
  
  

If your recommendation was stopped incorrectly and you wish a correction to be made, go to How do I report errors? Why might my recommendations have been moved to another analyst?

• You moved it: You or your firm may have simply transferred responsibility for the stock to another analyst.
  
  
• Shared coverage is not being assigned correctly: Sometimes Refinitiv will misinterpret the information the analyst's firm provides when more than one analyst cover a stock and make recommendations jointly.
