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.

For example, a value of 3 would produce 3 banded categories 2 cut pointseach containing cuargiles Specifies the method used to assign records to bins.
Note that if there are fewer discrete values in the data than the number of tiles specified, all tiles will not be used. 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. You may also specify whether the extension decilds added to the start Prefix or end Suffix of the field name. Percehtiles the simplified example above, the desired number of items per bin is 1.
Show details Hide details. A tie condition results when values on either side of a cut point are identical. Note that N in this case will not be replaced by the custom number.
IMSTAT Procedure (Analytics)
For example, a pharmaceutical company might rank physicians into decile groups based on the number aclculo prescriptions they write. The table below illustrates how simplified field values are ranked as quartiles when tiling by record count. When 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.
Note that this approach assumes that all values are greater than zero, and may yield unexpected results if this is not the case. Select to specify the decilee of bins. Select to allocate the tie values randomly to a bin. Keeps tie values in the current lower bin. Binning node dialog box Settings tab with options for equal count bins. See the topic Setting optimization options for streams for more information. Select to move the tie values up to the next bin. In Add to Cuartikes mode, it is added into bin 2.
Tiles (Equal Count or Sum)
This method may result in fewer total bins being created. 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 Percebtiles value 13 being value number 2 straddles the 1.
Seeks to assign an equal number of records to each bin. In Keep in Current mode, it is left in bin 1, pushing the range of values for bin percenyiles outside that of existing data values.
Tiles (Equal Count or Sum)
The speed of binning dediles tiles may benefit from enabling parallel processing. The threshold values for each bin are generated automatically based on the data and tiling method used.
Specify an extension used for field s generated using standard p-tiles. 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.
The thresholds of subsequent bins may also be adjusted as a result, causing values to be assigned differently for the same set of numbers based on the method used to resolve ties.
In such cases, the new distribution is likely to reflect the original distribution of your data. Records are ranked in ascending order based on the value of the specified bin field, so that records with the lowest values for the cuqrtiles bin variable are assigned a rank of 1, the next set of records are ranked 2, and so on.
As a result, only three bins are created, and the thresholds for each bin are adjusted accordingly. Ties can be moved up to the next 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.
Thresholds for generated bins. Specify an extension used for a custom tile range.
