## 24 Days of R: Day 19

December 19, 2013
By

Carrying on with the multi-level model, I'm going to look at the paid and incurred workers comp losses for a large number of insurance companies. This is a similar exercise to what I did last night, but I'm now working with real, rather than simulated data and the stochastic process is assumed to be different.

## Twelve Days 2013: Sensor Fusion

December 18, 2013
By

Day Seven: Sensor Fusion TL/DR Sensor fusion is a generic term for techniques that address the issue of combining multiple noisy estimates of state in an optimal fashion. There’s a straight forward view of it as the gain on a Kalman–Bucy filter, and an even simpler interpretation under the central limit theorem. A Primer on Stochastic Control Control theory is...

## New version of analogue on CRAN

December 14, 2013
By

It has been almost a year since the last release of the analogue package. At lot has happened in the intervening period and although I’ve been busy with a new job in a new country and coding on several other R packages, activity on analogue has also progressed a pace. As the version 0.12-0 of the package hits a...

## Understanding the data analytics project life cycle

December 12, 2013
By

While dealing with the data analytics projects, there are some fixed tasks that should be followed to get the expected output. So here we are going to build a data analytics project cycle, which will be a set of standard data-driven processes to lead data to insights effectively. The defined data analytics processes of a The post Understanding...

## Thursday: Scalable Cross-Platform R-Based Predictive Analytics

December 11, 2013
By

Tomorrow at 11AM Pacific Time, Revolution Analytics' Chief Scientist Mario Inchiosa will present a live webinar on Scalable Cross-Platform R-Based Predictive Analytics. Here's the abstract: In this webinar we will take a quick tour through an end-to-end predictive analytics session. We will start by exploring our data with summaries and histograms. Using the knowledge gleaned from data exploration, we...

## The forestplot of dreams

December 8, 2013
By

Displaying large regression models without overwhelming the reader can be challenging. I believe that forestplots are amazingly well suited for this. The plot gives a quick understanding of the estimates position in comparison to other estimates, while also showcasing the uncertainty. This project started with some minor tweaks to prof. Thomas Lumleys forestplot and ended up in a...

## Unobserved Effects With Panel Data

December 4, 2013
By

It is common for researchers to be concerned about unobserved effects being correlated with observed explanatory variables.For instance, if we were curious about the effect of meditation on emotional stability we may be concerned that there might be so...

## Maximizing Return from Every Item in the Marketing Research Questionnaire

December 3, 2013
By

Consumers will not complete long questionnaires, so marketing research must get the most it can from every item.  In this post, we look into the toolbox of R packages and search for statistical models that enable us to learn a great deal about eac...
