we are comparing performance vs normal bivariate data an non normal bivariate. Non parametric methods include spearman and kendalls and permuatation, parametric includes normal regression

Subtopic 2: Simulation study of parametric vs. nonparametric methods for bivariate data Conduct a simulation study to compare the performance of parametric vs. nonparametric methods for bivariate data. You may use as your measure of performance the percentage of times your hypothesis test rejects Ho when Ho is true and when Ho is false. Suggestions: Refer to the simulation study in class. Consider the effect of different sample sizes and distributions. For a complete answer, you must consider non-Normal data. Arrange the comparison of results clearly. Consider the relative importance of Type I and Type II errors. You may use the following code to generate from a double exponential distribution, which has heavy tails: rexptt
