## Hazardous and Benign Space Objects: Orbits in the Solar-Ecliptic Reference Frame

$Hazardous and Benign Space Objects: Orbits in the Solar-Ecliptic Reference Frame$

In two previous posts in this series I have wrangled NEO orbital data into R and then solved Kepler’s Equation to get the eccentric anomaly for each NEO. The final stage in the visualisation of the NEO orbits will be the transformation of locations from the respective orbital planes into a single reference frame. Reference

## stopping rule impact

Here is a question from my friend Shravan Vasishth about the consequences of using a stopping rule: Psycholinguists and psychologists often adopt the following type of data-gathering procedure: The experimenter gathers n data points, then checks for significance (p<0.05 or not). If it’s not significant, he gets more data (n more data points). Since time

$Hazardous and Benign Space Objects: Solving Kepler’s Equation$

Following on from my previous post about Near Earth Objects, today we are going to solve Kepler’s Equation to find the eccentric anomaly, which is the next step towards plotting the positions of these NEOs relative to Earth. The Eccentric, True and Mean Anomalies The relationship between the eccentric and true anomalies are depicted in

## ARIMA models with long lags

May 7, 2014
By

Today’s email question: I work within a government budget office and sometimes have to forecast fairly simple time series several quarters into the future. Auto.arima() works great and I often get something along the lines of: ARIMA(0,0,1)(1,1,0) with drift as the lowest AICc. However, my boss (who does not use R) takes issue with low-order AR and MA because...

## Relation of Word Order and Compression Ratio and Degree of Structure

May 7, 2014
By

Having a habit of compulsively wondering approximately every 34.765th day about how zip compression (bzip2 in this case) might be used to measure information contained in data – this time the question popped up in my head of whether or … Continue reading →

## How much code have you written?

This past week I attended the National Water Quality Monitoring Conference in Cincinnati. Aside from spending my time attending talks, workshops, and meeting like-minded individuals, I spent an unhealthy amount of time in the hotel bar working on this blog post. My past experiences mixing coding and beer have suggested the two don’t mix, but

## There is no “Too Big” Data, is there?

$Y_i\sim\mathcal{B}(p_i)$

A few years ago, a former classmate came back to me with a simple problem. He was working for some insurance company (and still is, don’t worry, chatting with me is not yet a reason for dismissal), and his problem was that their dataset was too large to run (standard) codes to get a regression, and some predictions. My...

## Object Oriented Programming with R: An example with a Cournot duopoly

April 23, 2014
By
$P(q) = q^{-\dfrac{1}{\eta}$

I started reading Applied Computational Economics & Finance by Mario J. Miranda and Paul L. Fackler. It is a very interesting book that I recommend to every one of my colleagues. The only issue I have with this book, is that the programming language they use is Matlab, which is proprietary. While there is a free...
