A simple trick for discovering missing data values is sorting the field of interest from largest to smallest values and then from smallest to largest values. This will let you more easily see null values, zero values, or extremely large or small values. This may provide clues for identifying ...
The covering machine learning algorithm CN4, a large extension of the well-known CN2 algorithm, is used here as an inductive vehicle. Each of the six routines for unknown attribute value processing (which are available in CN4) is used independently in order to process a given database. ...
a. What are the several ways of dealing with missing data? b. Discuss the advantages of one way tabulations. Tabulation : Tabulation refers to a method, which focuses on dividing the data into various different parts and, each part has subtotals a...
Nanotechnology offers society economic and technological opportunities, but technological innovations pose a challenge to governance of human and environmental safety due to the large difference in the pace between innovation and the development of suited governance. In order to cope with this change in ...

A repeated analysis could uncover further differences among “Before COVID-19,”“With COVID-19,” and “After COVID-19” (pre/in/post) periods based on an updated and enlarged dataset, possibly extending the databased to other websites. The empirical bases of analysis is restricted to ...
In a cross-sectional (Study 1; N = 99) and a 5-wave diary study (Study 2; N = 227), we examined whether self-compassion helps job seekers to better cope emotionally with the difficulties they encounter (Study 1) and the lack of progress they experience (Study 2) during job...
