Chapter 3, Problem 15PP
The Social Security Administration maintains an actuarial life table that contains the probability that a person in the United States will die (http://www.ssa.gov/OACT/STATS/table4c6.html). The death probabilities for 2009 are stored in the file LifeDeathProbabi1ity. txt, which is included on the website for the book. There are three values for each row: the age, the death probability for a male, and the death probability for a female. For example, the first five lines are
0 0.006990 0.005728
1 0.000447 0.000373
2 0.000301 0.000241
3 0.000233 0.000186
4 0.000177 0.000150
The interpretation for the fourth line is that a 3-year-old female has a 0.000186 chance of dying during year 3 to 4.
Write a program that inputs an age and sex from the keyboard in the main function. The main function should call a function named simulate (that you must write), sending in the age and sex as parameters. The function should simulate to what age a person will live by starting with the death probability for the given age and sex. You can do this by reading the data from the file row by row. Skip rows that are less than the input age. Once the input age is reached, generate a random number between 0 and 1, and if this number is less than or equal to the corresponding death probability, then predict that the person will live to the current age and return that age. If the random number is greater than the death probability, then increase the age by one and repeat the calculation for the next row in the file.
If the simulation reaches age 120, then stop and predict that the user will live to 120. The main function should output the simulated age at which the person will die. This program is merely a simulation and will give different results each time it is run, assuming you change the seed for the random number generator.

- # Create Custom Transformer Create a custom transformer, just as we did in the lecture video entitled "Custom Transformers", that performs two computations: 1. Adds an attribute to the end of the numerical data (i.e. new last column) that is equal to $\frac{x_1^3}{x_5}$ for each observation. In other words, for each instance, you will cube the $x_1$ column and then divide by the $x_5$ column. 2. Drops the entire $x_4$ feature column if the passed function argument `drop_x4` is `True` and doesn't drop the column if `drop_x4` is `False`. (See further instructions below.) You must name your custom transformer class `Assignment4Transformer`. Your class should include an input parameter called `drop_x4` with a default value of `True` that deletes the $x_4$ feature column when its value is `True`, but preserves the $x_4$ feature column when you pass a value of `False`. This transformer will be used in a pipeline. In that pipeline, an imputer will be run *before* this transformer. Keep…arrow_forward2.
