create indicator variables manually by usingdummyvar. Then use the indicator variables, except the one corresponding to the reference level of the categorical variable, when you fit a model. For the categorical predictorX, if you specify all columns ofdummyvar(X)and an intercept term as predictor...

However, if we require the execution of an ordered sequence of Matlab statements (commands) then it is sensible for these statements to be typed in the Matlab editor window to create a script which must be saved under a suitable name for future use as required. There will be no execution ...
To use the dummy variables in a regression model, you must either delete a column (to create a reference group) or fit a regression model with no intercept term. For the gender example, you need only one dummy variable to represent two genders. Notice what happens if you add an intercept...

You can set the true misclassification cost per class by using theCostname-value argument when you create the classifier.Cost(i,j)is the cost of classifying an observation into classjwhen its true class isi. By default,Cost(i,j)=1ifi~=j, andCost(i,j)=0ifi=j. In other words, the ...
