WebWe can compute the network score of a particular graph for a particular data set with the score() function ; if the score function is not specified, the BIC score is returned for both continuous and discrete data. > score (learn.net, learning.test) [1] -24006.73 WebThe test. In the score test, the null hypothesis is rejected if the score statistic exceeds a pre-determined critical value, that is, if. The size of the test can be approximated by its asymptotic value where is the distribution function of a Chi-square random variable with degrees of freedom.. We can choose so as to achieve a pre-determined size, as follows: WebThe best possible score is 1.0 and it can be negative (because the model can be arbitrarily worse). A constant model that always predicts the expected value of y, disregarding the input features, would get a \(R^2\) score of 0.0.

In statistics, the score (or informant ) is the gradient of the log-likelihood function with respect to the parameter vector. Evaluated at a particular point of the parameter vector, the score indicates the steepness of the log-likelihood function and thereby the sensitivity to infinitesimal changes to the parameter values.
