P-values. T-tests. Categorical variables. All are contenders for the most misused statistical technique or data science tool. Yet factor analysis is a whole different ball game. Though far … See more There are a plethora of factor extraction techniques, the merits of most of which are compared in this (useful) thrill-a-minute thesis. Here is what you need to know. There are … See more Though there are myriad indicators for the 'proper' number of factors to extract, there are two main techniques, other than the time-honored tradition of inspecting various factor … See more Factor extraction is one thing, but they are usually difficult to interpret, which arguably defeats the whole point of this exercise. To adjust for this, it is common to 'rotate', or choose slightly different axes in the n-factor subspace so … See more WebEqual Variances. Unlike in least squares estimation of normal-response models, variances are not assumed to be equal in the maximum likelihood estimation of logistic, Poisson, and other generalized linear models. For these models there is usually a known relationship between the mean and the variance such that the variance cannot be constant. sveti petar u sumi kroatien
