To train (create) a classifier, the fitting function estimates the parameters of a Gaussian distribution for each class (see Creating Discriminant Analysis Model).. To predict the classes of new data, the trained classifier finds the class with the smallest misclassification cost (see Prediction Using Discriminant Analysis Models). Probability Density Function . Online notes only serve as optional supplemental readings, and will not directly correspond to the lectures or textbook (see content). Using LDA and QDA requires computing the log-posterior which depends on the class priors \(P(y=k)\), the class means \(\mu_k\), and the covariance matrices..

Probability Mass Function. Correlation coefficients are used to measure how strong a relationship is between two variables.There are several types of correlation coefficient, but the most popular is Pearson’s. For example, height and weight of gira es have positive covariance because when one is big the other tends also to be big.

Covariance is a measure of how much two random variables vary together. Mathematically, this means that the covariance between the two isn't zero. In particular, if we have a SRS (simple random sample) without replacement, from a population with variance , then the covariance of two of the different sample values is , where N is the population size. Rule 7. We use the following formula to compute population covariance. \end{align} Estimation algorithms¶. That complicates the computations.
