Q9 Dо text mining using the аttаched dаta tweet_data_2022.csv. Use оbservatiоns 2001 through 3000. You should only use columns 2 and 10 for text mining. Also, the name of column 2 must be converted to "doc_id" and the name of column 10 must be converted to "text". For this, please refer to the following code. original_corpusdf2

[Dаtа Stаtic Hоldоut Methоd] Answer the questions using the "profootballhallofFame.csv". The dependent variable is "HOFm." 1) When using the three methods, enter the AIC of the model with the smallest AIC by each method. Round to 3 decimal places. You may use the following function, round(num,3)(If the number ends with '0', don't enter 0. For example, 1.230 (x) => 1.23 (o)) Forward selection: [value1] Backward elimination: [value2] Stepwise: [value3] Then, answer the following questions using the three linear regression models with the smallest AIC derived from the three methods above. 2) Create a static training set and static validation set using the following conditions. static training set: observation(row)# 1~100 static validation set: observation(row)# 101~153 Then, run the three linear regression models using the static training set,Next, enter the RMSE of each regression model derived by the static training set by using the static validation set. Round to 3 decimal places. RMSE of the linear regression model derived from Forward Selection method [value4] RMSE of the linear regression model derived from Backward Elimination method [value5] RMSE of the linear regression model derived from Stepwise method [value6] 3) Are the linear regression model with the minimum AIC and the model with the minimum RMSE value consistent? If they match, enter 1. If they do not match, enter 0. [value7]
