The least mean square (LMS) algorithm assumes a linear model of the form f(x)=θTx, with θ∈Rd, and a mean squared error loss function E(θ)=E[ei2] [1,2]. It is based on the stochastic gradient descent method, thereby, at each time instant ti,i=1,…,N, the instantaneous er...

What is being squared? In what sense are the squares "least"? R2 R2 Coefficient of Determination: The coefficient of determination shows the relationship between explanatory and explained variables. This is often defined as "R-Squared". The higher the...
We successfully validated a revision of the CATI. A confirmatory factor analysis supported the six-subscale structure (two-factor bifactors model: Chi-squared = 2705.73,p< .001, RMSEA = .04, SRMR = .03, CFI = .95, TLI = .94). Spearman’s rank correlations showed positive relationships ...

In statistics, ordinary least squares (OLS) or linear least squares is a method for estimating the unknown parameters in a linear regression model. This method minimizes the sum of squared vertical distances between the observed responses in the dataset, and the responses predicted by the linear ...
it reduces the relevance of large residuals since it is defined in terms of the absolute value of the errors instead of the squared errors. The median regression, through its weighting system, splits the residuals in exactly two halves, half above and half below the estimated regression line....
