Real Microsoft 70-773 Dumps1.You have a dataset that has multiple blocks and only numericvariables.You are computing in a local compute context.You plan to lag a variable named x to create a new variable namedx_lagged by using a transform function. You will create a new elementin the output of the function.You need to minimize the number of missing values.Which three actions should you perform? Each correct answerpresents part of the solution.NOTE: Each correct selection is worth one point.A. Assign a value to the first value of x_lagged in the current block.B. Use rxSet to store the last value of x_lagged in the current block.C. Use rxSet to store the last value of x in the current block.D. Use rxGet to retrieve the first value of x in the next block to beprocessed.E. Use rxGet to retrieve a value stored in processing of the prior block.Answer: ACD2.You need to use the ScaleR distributed processing in an ApacheHadoop environment.Which data source should you use?3.You have one class support vector machines (SVMs).You have a large dataset, but you do not have enough training time tofully test the model.page 1 / 13
What is an alternative method to validate the model?4.DRAG DROPYou 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 .impropriate values to the correct targets. Eachvalue may be used once, more than once, or not .You may need todrag the split bar between panes or scroll to view content.NOTE: Each correct selection is worth one point.Answer:page 2 / 13
