You perform an analysis that produces the decision tree shown in the exhibit. (Click the Exhibit button.)

How many leaf nodes are there on the tree?

You have a dataset.
You need to repeatedly split randomly the dataset so that 80 percent of the data is used as a training set and
the remaining 20 percent is used as a test set.
Which method should you use?

You need to build a model that looks at the probability of an outcome. You must regulate between L1 and L2.
Which classification method should you use?

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:

You have one-class support vector machines (SVMs).
You have a large dataset, but you do not have enough training time to fully test the model.
What is an alternative method to validate the model?

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 <- 5
02
03 (form, data = “segmentationDataBig”, maxDepth = maxdepth, cp = cp, xval = xval, blocksPerRead = 250
You need to complete the R code. The solution must support chunking.
Which function should insert at line 02?

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 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?

answer choice may be correct for more than one question in the series. Each question is independent

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.

You need to generate a residual based on two columns. The solution must build a trend indicator.
