Question restatement: - We are asked to define the test status (TP/TN/FP/FN) of the cows in the given table. The table provides, for each cow/date entry, a Gold standard value from Milk progesterone, a Peak activity change value, a Threshold indicator (whether Peak activity change on at least one day > 30), a 3 days block indicator (Threshold > 30 within a 3-day block), and the Test status (to be filled as TP/TN/FP/FN). - The dataset includes multiple rows for cows identified by number 1219, 1286, 1306, 1399, 1431, 1460 with various dates. The answer field accompanying the data lists the intended labels for each row in sequence: [TP, TN, FP, TN, FN, TN, TP, FN, TN, FN]. There are no multiple-choice options provided in this question; instead, the task is to classify each row according to the standard TP/TN/FP/FN definitions. Understanding how to determine TP/TN/FP/FN from the data: - Conceptually, a True Positive (TP) would occur when the Gold standard indicates a positive condition (e.g., 1 for progesterone indicating pregnancy/pregnancy-like status) and the test also indicates a positive result (Test status = 1). - A True Negative (TN) would occur when the Gold standard indicates a negative condition (e.g., 0) and the......Login to view full explanation

Consider the targeted marketing campaign case of selling products through promotional catalogs. The following tables show the confusion matrices of the classification tree model and the logit regression model, which classifies customers into 'likely to respond' (positive) and 'not likely to respond' (negative). Confusion Matrix of the Classification Tree Model: p (actual) n (actual) p (predicted) 10 4 n (predicted) 3 15   Confusion Matrix of the Logit Regression Model: p (actual) n (actual) p (predicted) 13 5 n (predicted) 2 12 Which model is more accurate (higher accuracy rate) based on the information given in these confusion matrices?

Which factor(s) will increase when the prediction agrees with the gold standard.

The sum true positives + false negatives equals:

A model was developed to classify whether or not tweets were written by a Twitter bot. The results from using the classification model on 24 tweets are shown below in the confusion matrix. Use the confusion matrix to answer the following questions. Give your answers as percentages rounded to one decimal place e.g. 23.1% or 42.0%. The accuracy of the classification model (PCC) was [Fill in the blank], %. [Fill in the blank], % of the tweets were predicted to be written by a bot. Of the tweets that were actually written by a bot, [Fill in the blank], % were correctly predicted to be written by bot. Of the tweets that were actually written by a bot, [Fill in the blank], % were incorrectly predicted to not be written by bot.
