where the outcomeYiis coded 0 or 1 for study subjecti,andxiis that subject's value of the predictor variable. Once again,ais a constant, in this case related to theprobabilityof the disease when the predictor is equal to zero, andbsummarizes the strength of the association; in this case...
So we have all the variants in Y. Then we have some predictor variable X. Batting average or on base percentage. QED This means, for example, that the predictor variables are assumed to be error-free—that is, not contaminated with measurement errors. WikiMatrix Gender, professional status...

Importance = permutationImportance(Mdl,X,Y) computes predictor importance values by using the predictors in the matrix X and the response values in variable Y. Importance = permutationImportance(___,Name=Value) specifies options using one or more name-value arguments in addition to any of the in...

PosteriorMdl = estimate(PriorMdl,X,y) returns the model that characterizes the joint posterior distributions of β and σ2 of a Bayesian linear regression model. estimate also performs predictor variable selection. PriorMdl specifies the joint prior distribution of the parameters, the structure of th...
New predictor values, specified as a vector, matrix, table, or dataset array. If you pass multiple inputsXnew1,Xnew2,...,Xnewnand each includes observations for one predictor variable, then each input must be a vector. Each vector must have the same size. If you specify a predictor var...
The fatal or injury type crash occurrence in a cloverleaf or diamond interchange was taken as the dependent variable with the “Other” type as the reference category. Among the predictor variables, the freeway AADT, the ramp ADT, the speed difference between the freeway and the ramp, the ...
Scatter plot of the average predicted vs observed BMI for the RF models. Dashed line, best-fit line; continuous line, x = y line. Full size image Through permutation of the OOB data, and within the imputation loop, we could obtain the scaled average variable importance of the different...
The function "predictorImportance" is a method of the "RegressionTree" class. When MATLAB starts, the "RegressionTree" classes are not loaded so the methods of these classes are not available at this point. Hence, one may get an error message like "Undef...
