getUDummyMatForOneVec

Create a U-dummy matrix for one variable

Provides functions to fit Accurate Generalized Linear Model (AGLM) models, visualize them, and predict for new data. AGLM is defined as a regularized GLM which applies a sort of feature transformations using a discretization of numerical features and specific coding methodologies of dummy variables. For more information on AGLM, see Suguru Fujita, Toyoto Tanaka, Kenji Kondo and Hirokazu Iwasawa (2020) <https://www.institutdesactuaires.com/global/gene/link.php?doc_id=16273&fg=1>.

getUDummyMatForOneVec function

<dl><dt>x_vec</dt>
<dd>A vector representing original variable.
The class of <code>x_vec</code> should be one of <code>integer</code>, <code>character</code>, or <code>factor</code>.</dd>
<dt>levels</dt>
<dd>A character vector representing values of <code>x_vec</code> used to create U-dummies.
If <code>NULL</code>, all the unique values of <code>x_vec</code> are used to create dummies.</dd>
<dt>drop_last</dt>
<dd>If <code>TRUE</code>, the last column of the resulting matrix is dropped to avoid multicollinearity.</dd>
<dt>only_info</dt>
<dd>If <code>TRUE</code>, only information fields of returned values are filled and no dummy matrix is returned.</dd></dl>
