To improve on the regression model, the researcher would have to try out other explanatory variables that could provide a more accurate fit to the data. If, for example, some students had seen the answers ahead of time, the regression model would then have two explanatory variables: time stud...
The effect of walking velocity on force platform measures is examined by means of functional regression and nonfunctional regression analyses. The two techniques are compared using a data set of ground reaction forces. Functional data analysis avoids the need to identify significant points, and provide...
In contrast to the conventional minimum mean square error (MMSE)-based noise reduction techniques, we propose a supervised method to enhance speech by means of finding a mapping function between noisy and clean speech signals based on deep neural networks (DNNs). In order to be able to handle...
I have found that having code to address a specific statistical problem is a very effective way for a student to learn a statistical software package. The author’s supplementary material using all three packages will provide an effective means for a student to learn multiple software packages ...
In addition to illuminating content necessary for coursework, the accessibility of this approach means students are more likely to be able to conduct research using MR or SEM--and more likely to use the methods wisely. Covers both MR and SEM, while explaining their relevance to one another ...
An approach using ordinary least squares (OLS) to fit a heteroscedastic regression model can accommodate nonstationarity in both the mean and variance of flood series while simultaneously offering a means of (i) analytically evaluating type I and type II trend detection errors, (ii) analytically ...
In practice, the W matrix is not computed explicitly because its size could be huge. If you had 1,000 rows of training data, matrix W would have 1,000,000 cells. Notice the beta update equation has a term W[t-1]X, which means the matrix product of W[t-1] and X. Because most...
Controlling for income means comparing the average monthly spending by the two groups (i.e., customers who accepted the card and customers who did not) within a particular income category. Again, you assumed that income is the only difference between the two groups. Given this assumption ...
A series of models is created; the first containing the variable with most empirical support, the second containing the first variable and the next most-supported, and so on. The comparatively small number of resultant models (n = the number of predictor variables) means that post-hoc ...
