Despite their impressive performance in most clinical prediction tests, neural networks are difficult to implement in the real clinical world due to the fact that they are black-box models and thus lack interpretability. Give at least 5 reasons why samples are used instead of population when conducting a research. {"appState":{"pageLoadApiCallsStatus":true},"articleState":{"article":{"headers":{"creationTime":"2016-03-26T15:39:13+00:00","modifiedTime":"2016-03-26T15:39:13+00:00","timestamp":"2022-09-14T18:05:51+00:00"},"data":{"breadcrumbs":[{"name":"Academics & The Arts","_links":{"self":"https://dummies-api.dummies.com/v2/categories/33662"},"slug":"academics-the-arts","categoryId":33662},{"name":"Math","_links":{"self":"https://dummies-api.dummies.com/v2/categories/33720"},"slug":"math","categoryId":33720},{"name":"Statistics","_links":{"self":"https://dummies-api.dummies.com/v2/categories/33728"},"slug":"statistics","categoryId":33728}],"title":"Statistics: Discrete and Continuous Random Variables","strippedTitle":"statistics: discrete and continuous random variables","slug":"statistics-discrete-and-continuous-random-variables","canonicalUrl":"","seo":{"metaDescription":"In statistics, numerical random variables represent counts and measurements. How do you apply RFs in these cases? What separates continuous random variables from discrete ones is that they are uncountably infinite; they have too many possible values to list out or to count and/or they can be measured to a high level of precision (such as the level of smog in the air in Los Angeles on a given day, measured in parts per million). ." classification - Is it normal that a classifier always wrongly predicts The number of winners in lotto for each day discrete 3. 1. 3x-2 2. the number of female students.

Classify the following random variables as discrete or continuous:X: the number of automobile accidents per year in Virginia. Even though the decision trees are randomized (a thorough explanation of random_state can be found in this question), they still rely on an internal criterion (such as Gini index by default in RandomForestClassifier) to split the nodes and define decision paths. What do you mean by "on the same sample". Assuming that the marks obtained by the children follow a normal distributed, find the number of children who have scored (i).
