Choose all that apply.Now compute the F1 score for all labels jointly: What is the sensitivity and specificity of a pneumonia model that always outputs positive? In other words, the models says that every patient has the disease.You have a model such that the lowest score for a positive example is higher than the maximum score for a negative example. What is its ROC AUC?You are working with the penguins dataset. You want to use the summarize() and mean() functions to find the mean value for the variable body_mass_g. You write the following code:penguins…What is the total loss from the normal (non-mass) examples in this example dataset?Use the following entry in SNOMED CT to help determine the positive labels for this x-ray report.Compute the Harrell C-index for the following dataset and risk scores:Compute the probability of surviving up to 4 years S(4)S(4) given the following dataset using the Kaplan Meier estimate:Compute S(5) given the following dataset using the Kaplan Meier estimate (note, it's the same dataset as in the previous question).In some studies, you may have to compute the Positive predictive value (PPV) from the sensitivity, specificity and prevalence.Now let’s say F1 score is at least 0.75. Now which of the following values of precision are possible? Based on these insights, you create your primary message. Which of the following reflect the expectations of a primary message?You are working with the diamonds dataset. You create a bar chart with the following code:ggplot(data = diamonds) +geom_bar(mapping = aes(x = color, fill = cut)) +You want to use the facet_wrap()…You are working with the diamonds dataset.
