Briefing 70-773: Analyzing Big Data with Microsoft R

Which three actions should you perform?

You have a dataset that has multiple blocks and only numeric variables.
You are computing in a local compute context.
You plan to lag a variable named x to create a new variable named x_lagged by using a transform function. You
will create a new element in the output of the function.
You need to minimize the number of missing values.
Which three actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

You are running a large logistic regression for 1,000 feature variables by using the LoisticRegression() function
in the MicrosoftML package. All of the predictor variables are numeric.Currently, you specify the input variables separately by using the following formula.
Outcome ~ Feature000 + Feature001 + Feature002 + … + Feature999
You discover that it takes 20 minutes to estimate each model.
You need to reduce the amount of time required to estimate each model without losing any information in the
predictors.
What should you do?

Which statement should you use for each environment?

DRAG DROP
You need to set the compute context for three different target environments.
Which statement should you use for each environment? To answer, drag the appropriate statements to the
correct execution contexts. Each statement 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.
