That is the case of a study based on a stepwise regression linear technique which by using variables such as amplitude, frequency and periodicity, demonstrated that the percentage of unvoiced segments explains a significant part of the variance of the total scores obtained from various ...
The fixed portion of (1), Xβ, is analogous to the linear predictor from a standard OLS regression model with β being the regression coefficients to be estimated. For the random portion of (1), Zu + , we assume that u has variance–covariance matrix G and that u is orthogonal to so...
[33]. The uniform bound, however, can be obtained from testing a complete set of orthogonal contrasts using the Studentized Maximum Modulus Distribution [34]. In practice, although a little bit conservative, it is straightforward to use this uniform bound to test all contrasts especially when ...
What if, for example, you had a factor with three levels, A, B, and C, with means 3, 5, and 4. If C is the reference level, could it be the case in the regression model that neither the coefficient comparing A to C nor the coefficient comparing B to C would be significantly di...
The images from thedatabase are ranked by their evaluated relevance probability to the given query by using low-level visual features. The relevance, or similarity, of each of the images to the given query is estimated by several generalized linear models, in particular local logistic regression ...
4. The output title, "Mixed-effects ML regression", informs us that our model was fit using ML, the default. For REML estimates, use the reml option. Because this model is a simple random-intercept model fit by ML, it would be equivalent to using xtreg with its mle option. 5. The ...
