053=0.017 significance level (P = 0.0019), and patients with intermediate-term OS also had significantly higher expression levels than patients with long-term OS (P Histone demethylase survival).

Table 4 AIC-selected model sensitivity and specificity for predicting short-term survival and for predicting short- or intermediate-term survival.

A common critique of a model fitted from high-dimensional data is that the final model, even if selected by minimizing AIC, is not parsimonious. In this example, critics may say that given a sample size of 69 subjects, including 25 coefficients in Selleckchem Venetoclax the model is overfitting, and that the model performance is likely a result of chance. In response, we fit two additional models whose performances will be a result of chance alone. First, we fit a model with the same gene-expression data used in our example, but we randomly permuted the response vector. Next, we fit a model using our original response vector, but instead of using the gene expression data, we used a design matrix filled with 31,744 �� 69 = 2,190,336 random variables generated from a Gaussian distribution with a mean and standard deviation equal to the corresponding sample statistics of the gene expression data. If we exclude regions of underfitting and overfitting, the model fit with the gene expression data and the original response vector had better performance than the other two models whose performances are a result of chance rather than a relationship between the features and the response (Fig. 4).
