4 days ago · Complementary metrics like MAE (Mean Absolute Error) or RMSE (Root Mean Squared Error) provide additional insights, ensuring a holistic evaluation of model performance.
3 days ago · The regression effect does not say that an individual who is a given number of SD from average in one variable must have a value of the other variable that is closer to average—merely that individuals who are a given number of SD from the mean in one variable tend on average to be fewer SD from the mean in the other.
1 day ago · Central limit theorem. In probability theory, the central limit theorem ( CLT) states that, under appropriate conditions, the distribution of a normalized version of the sample mean converges to a standard normal distribution. This holds even if the original variables themselves are not normally distributed.

4 days ago · d X t = f ( X t, t, p 1) d t + g ( X t, t, p 2) d W t ( 1) where X t = X ( t) is the realization of a stochastic process or random variable, f ( X t, t) is the drift coefficient, g ( X t, t) denotes the diffusion coefficient, the stochastic process W t is called Wiener process. For this SDE system, we can define two Python funtions f and g to ...
