### Numerical Analysis for Statisticians (Statistics and Computing)

If X is a random variable with a population mean and a population median , then. Thus, if the median minimizes , then, intuitively, it minimizes.

This post contains the R function that implements this method, the R functions that contain the 3 functions that were minimized by this method, and the R script that ran the minimization.

The first algorithm that I learned for root-finding in my undergraduate numerical analysis class MACM at Simon Fraser University was the bisection method. The bisection method can be easily adapted for optimizing 1-dimensional functions with a slight but intuitive modification. As there are numerous books and web sites on the bisection method, I will not dwell on it in my blog post.

In a later post for the sake of brevity , I will use the same method to show that the minimizer of the sum of the absolute deviations from a univariate data set is the median. The EM Algorithm.

### Technology Skills

From the reviews: "This book provides reasonably good coverage of numerical methods that are important in statistical applications. Consulting and other collaborative experience is highly desirable. The position is open to all citizens of the United States or legal permanent residents with a work authorization. Applicants are responsible for obtaining the necessary work authorization.

Experience and coursework in statistics are essential, as is experience collaborating on statistical applications; statistical computing and software for statistical analysis; and conducting research in theoretical statistics, modeling and small-area estimation, novel sample and study design, analysis of data from complex surveys, statistical disclosure limitation and confidentiality, missing data, or other current or emerging statistical areas. The successful candidate will be offered an initial month appointment, which may be extended. A starting date will be determined by mutual agreement.

Salary increases will be commensurate with performance. Federal benefits such as annual and sick leave, Thrift Savings k -equivalent, and health and life insurance apply.

A flexible work schedule or telework may be offered at the discretion of the division. Free onsite parking or a public transportation subsidy is available. The local subway station is within walking distance, and a free shuttle is available to and from the station.
