Properties that can be configured for the HANA Logarithmic Regression
algorithm.
Syntax Use this algorithm to find trends
in data. This algorithm performs bi-variate logarithmic regression analysis. It
determines how an individual variable influences another variable using a
Predictive Analysis Library (PAL) logarithmic function.
Note The data type of columns used during model
scoring should be same as the data type of columns used while building the
model.

Algorithm Properties
| Property |
Description |
| Output Mode |
Select the mode in which you want to use the output of this
algorithm.Possible values: - Fill: Fills missing values in the target column.
- Trend: Predicts the values for the dependent column and
adds an extra column in the output containing the
predicted values.
|
| Independent Column |
Select the input columns with which you want to perform the
regression analysis. |
| Dependent Column |
Select the target column for which you want to perform the
regression analysis. |
| Missing Values |
Select the method for handling missing values.Possible
methods: - Ignore: The algorithm skips the records containing
missing values in the independent or dependent columns.
- Keep: The algorithm retains the records containing
missing values during calculation.
|
| Predicted Column Name |
Enter a name for the newly-created column that contains the
predicted values. |
| Number of Threads |
Enter the number of threads that the algorithm should use during
execution. The default value is 1. |
