... 2. Regression: calculate the regression equation, r and R^2. (R^2=r*r gives the percentage of variation of the data explained by the model). R^2 is tiny, say<0.2, a linear model may not be a good choice. 3. Residuals: check the residual plot even when R^2 is large. Bad sign if we see some pattern. T ...

Expectation–maximization algorithm

In statistics, an expectation–maximization (EM) algorithm is an iterative method for finding maximum likelihood or maximum a posteriori (MAP) estimates of parameters in statistical models, where the model depends on unobserved latent variables. The EM iteration alternates between performing an expectation (E) step, which creates a function for the expectation of the log-likelihood evaluated using the current estimate for the parameters, and a maximization (M) step, which computes parameters maximizing the expected log-likelihood found on the E step. These parameter-estimates are then used to determine the distribution of the latent variables in the next E step.
