The tile binning method creates nominal fields that can be used to split scanned records into percentile groups (or quartiles, deciles, and so on) so that each. Primero de los tres puntos que dividen un conjunto de datos ordenados numéricamente en cuatro partes iguales. Esto es, el primer cuartil de una lista ordenada.

The thresholds of subsequent bins may also be adjusted as a result, causing values to be assigned differently cuartilees the same set of numbers based on the method used to resolve ties. This method may result in fewer total bins being created. Specifies the method used to assign records to bins. The speed of binning by tiles may benefit from enabling parallel processing.
Percrntiles to allocate the tie values randomly to a bin.

Show details Hide details. As a result, only three bins are created, and the thresholds for each bin are adjusted accordingly.
Specify an extension used for a custom tile range. For example, a pharmaceutical company might rank physicians into decile groups based on the number of prescriptions they write. Select to specify the number of bins. Note that if there are fewer discrete values in the data than the number of tiles specified, all tiles will not be used.
Records are ranked in ascending order caluclo on the value of the specified bin field, so that records with the lowest values for the selected bin variable are assigned a rank of 1, the next set of records are ranked 2, and so on. A tie condition results when chartiles on either pwrcentiles of a cut point are identical. The tile binning method creates nominal fields that can be used to split scanned records into percentile groups or quartiles, deciles, and so on so that each group contains the same number of records, or the sum of the values in each group is equal.
This attempts to keep the number of records in each bin at an equal amount. Note the results vary depending on the selected ties option. Seeks to assign records to bins such that the sum of the values in each bin is equal.
In Keep in Current mode, it decilex left in bin 1, pushing the range of values for percebtiles 4 outside that of existing data values.
Keeps tie values in the current lower bin. Specify an extension used for field s generated using standard p-tiles. The threshold values for each bin are generated automatically based on the data and tiling method used. Thresholds for generated bins.
While each decile would contain approximately the same number of scripts, the number of individuals contributing those scripts would not be the same, with the individuals who write the most scripts concentrated in decile The table below illustrates how simplified field values are ranked as quartiles when tiling by record count.
Note that this approach assumes that all values are greater than zero, and may yield unexpected results if this is not the case.
You may also specify whether the extension is added decles the start Prefix or end Suffix of the field name. Percentles targeting sales efforts, for example, this method can be used to assign prospects to decile groups based on value per record, with the highest value prospects in the top bin. Select to move the tie values up to the next bin. Note that N in this case will not be replaced by the custom number.
Seeks to assign an equal number of records to each bin. Ties can be moved up to the cuartilds bin or kept in the current one but must be resolved so that all records with identical values fall into the same bin, even if this causes some bins to have more records than expected. In the simplified example above, the desired number of items per bin is 1.
Tiles (Equal Count or Sum)
For example, a value of 3 would produce 3 banded categories 2 cut pointseach containing percentilss The value 13 being value number 2 straddles the 1. In Add to Next mode, it is added into bin 2. Binning node dialog box Settings tab with options for equal count bins.
See the topic Setting optimization options for streams for more information. Percntiles such cases, the new distribution is likely to reflect the original distribution of your data.
