У мене з’явилось враження що з лабою щось не так. CREATE OR REPLACE MODEL `bqml_dataset.predicts_visitor_model` OPTIONS (model_type='logistic_reg', labels = ['will_buy_on_return_visit']) AS SELECT fullvisitorid AS unique_session_id, # labels IFNULL(totals.transactions,0) as will_buy_on_return_visit, # mobile or desktop device.operatingSystem as operating_system, device.deviceCategory, # geographic IFNULL(geoNetwork.country, "") AS country, IFNULL(totals.pageviews, 0) AS pageviews FROM `bigquery-public-data.google_analytics_sample.ga_sessions_20170801` #Here you have to used the visitor's devices operating system, whether said device is a mobile device, the visitor's country and the number of page views as the criteria for whether a transaction has been made. Also you have to specify the model type as binary logistic regression #Create a model named 'predicts_visitor_model' in the precreated dataset 'bqml_dataset' that predicts whether a visitor will make a transaction. #Also, evaluate the model 'predicts_visitor_model'
