conf.mat.plot

parameter learning

Offers a suite of helper functions to simplify various data science techniques for non-experts. This package aims to enable individuals with only a minimal level of coding knowledge to become acquainted with these techniques in an accessible manner. Inspired by an ancient Persian idiom, we liken this process to "eating the liver of data science," suggesting a deep and intimate engagement with the field of data science. This package includes functions for tasks such as data partitioning for out-of-sample testing, calculating Mean Squared Error (MSE) to assess prediction accuracy, and data transformations (z-score and min-max). In addition to these helper functions, the 'liver' package also features several intriguing datasets valuable for multivariate analysis.

conf.mat.plot function

<dl> <dt>pred </dt>
<dd>a vector of estimated values.</dd> <dt>actual</dt>
<dd>a vector of actual values.</dd> <dt>cutoff</dt>
<dd>cutoff value for the case that <code>pred</code> is vector of probabilites.</dd>
 
 <dt>reference</dt>
<dd>a factor of classes to be used as the true results.</dd> <dt>conf.level</dt>
<dd>confidence level used for the confidence rings on the odds ratios. Must be a single nonnegative number less than 1; if set to 0 (the default), confidence rings are suppressed.</dd>
 
 <dt>margin</dt>
<dd>a numeric vector with the margins to equate. Must be one of 1 (the default), 2, or c(1, 2), which corresponds to standardizing the row, column, or both margins in each 2 by 2 table. Only used if std equals "margins".</dd>
 
 <dt>color</dt>
<dd>a vector of length 2 specifying the colors to use for the smaller and larger diagonals of each 2 by 2 table.</dd>
 
 <dt>... </dt>
<dd>options to be passed to <code>fourfoldplot</code>.</dd></dl>
