Including too many

The model is, in several aspects, a simplification of the processes that occur. As an example, it is important—and also possible when further data are available from experiments — to expand the model by including the oxidation of sulfide in a gravity sewer at low DO concentrations and the emission of hydrogen sulfide into the sewer atmosphere. From a general point of view, however, it is considered important only to deal with the most important aspects to keep the number of processes low and not include too many process parameters that are site specific. 

There are three eomponents to the empirieal approach of developing a predietive elas-sifier. The first component is determining whieh genes to inelude in the predietor. This is generally called feature seleetion. Including too many noise variables in the predictor usually reduces the aeeuracy of predietion. The second component is speeifieation of the mathematical function that will provide a prediction for any given expression veetor. 

Overfitting the PCR calibration model is easily accomplished by including too many factors. For this reason, it is very important to use test data to judge the performance of the calibration model. The test data set should be obtained from standards or samples prepared independently from the calibration data set. These test standards are treated as pseudo-unknown samples. In other words, the final PCR calibration model is used to estimate the concentration of these test samples. Using the harmonious approach noted in Figure 5.14 significantly reduces the chance of obtaining an overfitted model. 

Don t let your story lag or wander. At some time you ve probably listened to a storyteller who became stuck on some insignificant detail ( Was it Friday or Saturday the letter came Let s see now.. . . Then Joe said to me—no, it was Sally—no, wait, it was.. .. ). And you ve probably also heard bores who insist on making a short story long by including too many unimportant details or...

Pie charts best show parts of a whole. Be careful not to include too many slices since that results in a cluttered graph. Six slices are usually as many as can be handled on one pie. 

Number of terms. One should have at least five to six data points per variable to avoid chance correlations (this rule applies only to data sets of intermediate size for small data sets, more parameters may be allowed if they are based on a reasonable model for large data sets, e.g., n > 30, this recommendation leads to equations that include too many variables). 

The publisher asks you to review this problem. Make a recommendation about the validity of this rate law by writing a few sentences. In other words, does the rate law seem reasonable, or should it be modified If modification is required, indicate qualitatively how the modification should proceed. Please don t include too many equations because the publisher must read your review and decide whether a second edition of this textbook should be printed. All the engineering editors are on vacation in Hawaii. 

People new to the field often question the importance of significant figures, but they have great practical importance, for they are a quick way to tell how accurate a number is. Including too many can not only make your numbers harder to read, it can also have serious negative consequences. 

Your narration should convey only the story points needed to get to the next sync material if you go too far or include too many points, your audience will lose track of the information and will be... 

The range of costs for pulmonary function equipment is from less than 300 for simple spirometers to 50,000 for hospital body plethysmographs. The cost must be appropriate for the use. In general, home-use devices are much less costly then hospital devices. Home devices are usually much simpler and may not be as accurate or reliable as hospital devices. The design engineer must know the maiket for a new device before investing inordinate amounts of time or before including too many options that lead to inappropriate purchase prices. 

During calcination, the precursors are transformed to the desired oxide. The final temperature of the calcination depends on the formation temperature of the perovskite and on the nature of the precursor. The more homogeneous the precursor, the less harsh the calcination conditions are. In the case of sol-gel precursors, the temperature and time of calcination would normally have been reduced, since the diffusion distances are smaller. In our study, we have chosen, for the same sample prepared via different routes, the same temperature and calcination time, to enable the comparison of the different reactivities, without including too many parameters. 

Uses of chromimn (VI) include certain textile processes and leather taiming. It is highly toxic even at low concentrations, including too many aquatic organisms. Within the EU, cadmium, mercury and lead have been classified as priority hazardous substances under regulations that require measru es to be taken to eliminate their pollution of surface waters in Europe. Uses of cadmium, mercury and lead have been severely restricted in Europe for some time, including certain specific uses of mercury and cadmium in textiles. 

One of the key issues in initiating the CRIOP analysis has been to select the relevant checklist items and scenarios during the planning and preparation phase. The identified issues should be further explored in the subsequent CRIOP analysis. The scenario analysis is an important arena for exploring challenging situations. Experienced CCR operators should be involved to identify scenarios to be explored. Given the limited time available for a CRIOP analysis, it is important not to include too many questions or too many scenarios. The CRIOP analysis must not be performed as a defence, or...
