Note: This question is part of a series of questions that use the same or similar answer choices. An answer choice may be correct for more than one question in the series. Each question is independent of the other questions in this series. Information and details provided in a question apply only to that question.You need to estimate a model where the outcome variable is continuous, is in the range of [0, inf], and has a substantial mass at an exact value of 0.Which function should you use?
You have a Microsoft SQL Server instance that has R Services (In-Database) installed. The server has a comma-separated values (CSV) file stored in the local file system.For analytic purposes, you need to read the CSV file into a database table in the SQL Server instance.You connect to the SQL Server instance by using SQL Server Management Studio.What should you use from sp_execute_external_script?
You plan to read data from an Oracle database table and to store the data in the file system for later processing by dplyrXdf. The size of the data is larger than the memory on the server to be used for modelling.You need to ensure that the data can be processed by dplyrXdf in the least amount of time possible.How should you transfer the data from the Oracle database?
You are running a parallel function that uses the following R code segment. (Line numbers are included for reference only.)01 cp <- 0.01 xval <- 0 maxdepth <- 503 (form, data = "segmentationDataBig", maxDepth = maxdepth, cp = cp, xval = xval, blocksPerRead = 250You need to complete the R code. The solution must support chunking.Which function should insert at line 02?
DRAG DROP -You are using rxPredict for a logistic regression model.You need to obtain prediction standard errors and confidence intervals.Which R code segment should you use? To answer, drag the appropriate values to the correct targets. Each value may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.NOTE: Each correct selection is worth one point.Select and Place:
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.After you answer a question in this sections, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.You use dplyrXdf, and you discover that after you exit the session, the output files that were created were deleted.You need to prevent the files from being deleted.Solution: You use rxSetComputeContext with the local parameter before performing operations that save results.Does this meet the goal?
