Median inferences are appealing for fitting an ARMA model with heteroscedastic errors to financial returns, because such returns are known to have heavy tails. To ensure that the model is still related to the conditional mean, we test for a zero mean of the errors by us...
Next we usemarginsto focus on subjects who are susceptible to smoking. By specifying statisticpcond1along with each outcome level, we calculate the probability of each level oftobacco, conditional on susceptibility. As before, calculations are performed at five levels ofincomeand graphed withmargins...
It is well known that the Gaussian hypergeometric function,F(a,b;c;x), has a broad range of applications in geometric function theory, the theory of mean values, and numerous other areas within mathematics and related disciplines. Many elementary and special functions in mathematical physics are ...
The widely used cloud computing technology stores, processes, and manages data on remote servers centered on the Internet, providing users with a range of resources in the form of services. Although the efficiency of information sharing and the use of computer and storage resources has grown due ...
The middle part of the output reports the probit coefficients for the inflation. Coefficients can be difficult to interpret. For instance, what does a parent smoking coefficient of 0.72 mean? It means that, on average in the data, those whose parents are smokers are about 27% less likely to...
WHAT DOES NET-ZERO MEAN? According to the Net-Zero Standard released by the Science Based Target Initiatives, "Setting corporate net-zero targets aligned with meeting societal climate goals means (1) achieving a scale of value chain emissions reductions consistent with the depth of abatement at ...
For example, at snr = −2 dB, the up and down errors of the cae method is as high as about 27%. This is because the CAE learns the statistical distribution of input data during the training process. Therefore, if the training data cannot fully represent the complex noise conditions in...
Conditional on the large acquisition event, there is an increase in leverage and no reverse after a large acquisition. Second, some firms deliberately maintain persistent zero-leverage, although they can increase their firm value by utilizing a tax shield of debt. The CEOs of these ZL firms may...
If a function is given an incorrect number of errors GSL will print an error on the console and terminate. If the provided arguments are of the wrong type or otherwise incorrect, the functions will return an undefined result, which can be handled with the default operator and tested with the...
Today, fiber, copper, cable, and microwave technologies mean that networks can grow even faster. We already have the core of a global network, which is gradually being extended to every corner of the earth. The expansion of broadband coverage has been a major factor driving the incredible ...
