\nThis CA assesses students on core concept in Hypotheses tests, GLM analytics, and Bayesian analytics.
\nAll questions are mandatory.
\nUse R\/Rstudio to solve questions and perform analytics.
\nAny submission after deadline will not be considered and scored.
\nQuestion 1
\nConsider a relational dataset and specify your input and output variables , then:
\nTrain the model using 80% of this dataset and suggest an appropriate GLM to model ouput to input variables.
\n(10 Marks)
\nSpecify the significant variables on the output variable at the level of ??=0.05 and explore the related hypotheses test. Estimate the parameters of your model.
\n(10 Marks)
\nPredict the output of the test dataset using the trained model. Provide the functional form of the optimal predictive model.
\n(10 Marks)
\nProvide the confusion matrix and obtain the probability of correctness of predictions.
\n(5 Marks)
\n(Total: 35 Marks)
\nQuestion 2
\nLet x_1,\u2026,x_10 are identically independently distributed (iid) with Poisson(?).
\nCompute the likelihood function (LF). (10 Marks)
\nAdopt the appropriate conjugate prior to the parameter ? (Hint: Choose hyperparameters optionally within the support of distribution). (10 Marks)
\nUsing (a) and (b), find the posterior distribution of ?. (10 Marks)
\nCompute the minimum Bayesian risk estimator of ?. (5 Marks)
\n(Total: 35 Marks)
\nQuestion 3
\nAn opinion poll surveyed a simple random sample of 1000 students. Respondents were classified by gender (male or female) and by opinion (Reservation for women, No Reservation, or No Opinion). Results are shown in the observed contingency table below.
\nDoes the gender and opinion on women reservation are independent? Use a 0.05 level of significance. To do so,
\nState the hypotheses. (5 Marks)
\nFind the statistic and critical values. (10 Marks)
\nExplain your decision and Interpret results. (15 Marks)
