Variable Selection Sample Clauses

Variable Selection. Data can often be presented to prediction models in a multitude of ways, depending on the quality, complexity and completeness of the data. In traditional statistical techniques such as regression and decision trees, a missing value often leads to removal of that entire case from analysis and thus depending on the dataset, this can significantly reduce the number of available cases for analysis, reducing its statistical power (107). This can also lead to biased results and possible invalid conclusions (108). Within ANNs, missing data is treated in a much more fluid way, with incomplete cases still included in the network creation. This opens up the possibility of including a larger number of cases, and the ability to include more variables than possible traditional techniques. This raises difficulties of its own; the number of potential variables may be very large, correlation between variables may cause redundancy, variables may have negligible effect upon the model (109). The conundrum of how many and which variables to include can be dealt with by using an embedded technique, whereby variables are all entered into the model in the initial stage of training and gradually removed and the effect upon the resultant model assessed (see below).

Variable Selection. Of the 27 total questions, 16 questions of interest were selected for further analysis. Questions were selected for their relationship with our selected outcome of interest and for clinical significance based on previous literature. Our selected outcome of interest was defined as whether a participant believed that traditional herbal treatments could cure TB. Selected measures consisted of demographic information and responses for TB knowledge.

Variable Selection. My research will build upon previous research but will not examine the impact of the DIP on equity returns or differentiate firms based on whether they receive or do not receive a DIP. Dependent variables for my OLS modelling consisted of four calculated financial metrics from the BRD. The first, DIP size, was calculated as the sum of all DIP values in the BRD to produce an overall amount of funding provided during the bankruptcy. The majority of companies in distress receive one DIP, but some companies can receive two or more from different lenders. Thus, to provide an accurate picture of the total amount of funding given to the distressed companies, these values were summed. This value will be log transformed in my OLS models. The second metric, DIP risk, was estimated by dividing the total DIP size by the pool of assets the company reported on their last 10K report. This value can also be referred as a loan-to- value, or LTV, as the loan value is expressed as a fraction of the value of the underlying company assets. According to the literature (Xxxxxx et. Al 2003), this is a standard and theoretically acceptable form of calculating the risk of a transaction. The third and fourth metrics dealt with the time to completion for the DIP and bankruptcy, respectively. The first metric was the length of time from the filing date to the date the court entered its final order approving the DIP loan. The second metric was the length of time from the filing date to the case disposal date – the earlier of the date where the reorganization was confirmed, or the date where the case was converted to a Chapter 7 case or dismissed. I will log transform both of these variables in my OLS models. I also conducted a Probit analysis on a fifth dependent variable, the emergence of the distressed company from Chapter 11. Because this type of analysis has been well documented in literature on the full dataset with regards to the influence of corporate and bankruptcy conditions on emergence, especially by Carapeto (2003), I restricted the Probit analysis to just the 198 companies in my dataset. A company is considered to have emerged by the BRD if at least one operating company emerged from the bankruptcy under either a confirmed plan or 363 sale. My analysis is novel because it estimates the impact of the investment banker on emergence of the company, a model which has not yet been examined in the literature. The independent variable selection was formed based on the literature ...

Variable Selection. ‌ First, classic monotonic transformations of the metrics were used to meet the requirements of the linear model (normality, linearity): count (abundance, richness) and biomass metrics were log-transformed; proportion metrics were arcsine-square root transformed, whereas diversity indices were kept raw. The abundance metrics were computed two different ways:

The effective date will be on the first day of your employer’s plan year. Special Enrollment Period A Special Enrollment Period is a time outside the yearly Open Enrollment Period when you can sign up for health coverage.

Special note about enrolling your newborn child: You must notify your employer of the birth of a newborn child and pay the required premium within thirty -one (31) days of the date of birth. Otherwise, the newborn will not be covered beyond the thirty -one (31) day period. This plan does not cover services for a newborn child who remains hospitalized after thirty-one (31) days and has not been enrolled in this plan. If you are enrolled in an Individual Plan when your child is born, the coverage for thirty- one (31) days described above means your plan becomes a Family Plan for as long as your child is covered. Applicable Family Plan deductibles and maximum out-of-pocket expenses may apply.
