Logistic Regression VAL

In Logistic Regression, a set of independent variables (in this case, columns) is processed to predict the value of a dependent variable (column) that assumes two values referred to as response (1) and non-response (0).

Options

Backward Only
Specifies whether to use only backward technique or not, i.e. a forward step is not performed.
Backward
Specifies whether to take backward steps or not. Backward steps, i.e., removing variables from a model, use the P-value of the T-statistic, i.e., the ratio of a B-coefficient to its standard error.
Input columns
Specifies the name(s) of the column(s) representing the independent variables used in building a logistic regression model.
Conditional Independence Threshold
Specifies the condition index threshold value to use while generating near dependency report.
Constant
Specifies whether the logistic model includes a constant term or not.
Convergence
Specifies the convergence criterion such that the algorithm stops iterating when the change in log likelihood function falls below this value.
End Threshold
Specifies the ending threshold value utilized in the Multi-Threshold Success output.
Entrance Criterion
Specifies the criterion to enter a variable into the model. The W-statistic chi-square P-value must be less than this value for a variable to be added.
Forward Only
Specifies whether to use only forward technique or not, i.e. a backward step is not performed.
Forward
Specifies whether to use forward technique or not. Starting with no independent variables in the model, a forward step is performed, adding the 'best' choice, followed by a backward step, removing the worst choice
Group By columns
Specifies the name(s) of the column(s) dividing the input into partitions, one for each combination of values in the group by columns.
Increment Threshold
Specifies the difference in threshold values between adjacent rows in the Multi-Threshold Success output.
Lift Output
Specifies whether to build a lift chart or not and add it in the functions output string.
Matrix Data
Specifies the input matrix data to use for the analysis. Instead of internally building a matrix with the Matrix function each time this analysis is performed, the user may build an ESSCP Matrix.
Max Iteration
Specifies the maximum number of attempts to converge on a solution.
Memory Size
Specifies the memory size in megabytes to allocate for in-memory Logistic Regression.
XML Report
Specifies whether to produce an XML report showing columns that may be collinear as part of the output or not.
Remove Criterion
Specifies the criterion to remove a variable from the model. The T-Statistic P-value must be greater than this value for a variable to be removed.
Response Column
Specifies the name of the column that represents the dependent variable being predicted.
Response Value
Specifies the value assumed by the dependent column that is to be treated as the response value.
Sample
Specifies whether to use sample of the data to be read into memory for processing, if the memory size available is less than the amount of data to process.
Start Threshold
Specifies the beginning threshold value utilized in the Multi-Threshold Success output.
Stats Report
Specifies whether an optional data quality report should be delivered in the function's XML output string or not, which includes the mean and standard deviation of each model variable, derived from an ESSCP matrix.
Stepwise
Specifies whether to perform a stepwise procedure or not.
Sucess Output
Specifies whether an optional success report should be delivered in the function's XML output string or not, which includes the displaying counts of predicted versus actual values of the dependent variable of the logistic regression model.
Threshold Output
Specifies whether the Multi-Threshold Success output should be produced or not and included in the XML output string in the result.
Variance Proportion Threshold
Specifies the variance proportion threshold value to use while generating near dependency report.
