... negative values in log odds, and odds greater than one have positive values in log odds. This accords better with the natural number system which runs from -∞ to + ∞. If we take any two numbers and multiply them together that is the equivalent of adding their logs. Thus logs make it possible to conv ...

Allowing for ±0.5 or ±1 days of lag (0.1-0.2% of the IC40 year) gives a null test statistic distribution identical to not allowing a lag. This means the discovery potential curve will be ...

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.
