In general, this distribution is used when you have a smallsample size(under 30) or you don’t know the population standard deviation. For practical purposes (i.e. in the real world), this is nearly always the case. So, unlike in yourelementary statisticsclass, you’ll likely be using ...
Based on the several blog posts I came across, the weights for theConvTranspose2dlayer will be randomly initialized from a Normal distribution with mean=0, standard deviation=0.02. For theBatchNorm2dlayer, the mean and standard deviation of the distribution will be 1 and 0.02, respectively. Thi...
The log-likelihood function is lnL = ln(normalden(yj − (Xj × b :+ c), 0, sqrt(s2))) j where normalden(x, mean, sd) returns the density at x of the Gaussian normal with the specified mean and standard deviation; see [M-5] normal( ). The above is a two-parameter or, ...

However, the variables of marital status, race, religion, discharge disposition, hospital service, insurance/finance class, and PriorEDF were biased towards some specific values. Table 2 provides the mean and standard deviation (SD) of the numeric variables. Most numeric variables were clustered ...
The root–mean–square roughness (Rq) of film is about 31.3 nm. Furthermore, the particle size distribution histogram calculated on the SEM image is shown in Fig. 1d. Accordingly, the average granular grain size of PbS is approximately 119 nm. The formation of uniform compact grains...
