In Chapter 5 on basic regression, we’ll only consider models with a single explanatory variable xx. In Section 5.1, the explanatory variable will be numerical. This scenario is known as simple linear regression. In Section 5.2, the explanatory variable will be categorical....
In this chapter we will review some of the concepts that are needed later in the book. In particular, we focus on measurement theory and some basic elements of probability theory and fuzzy sets theory.

Applies to: Microsoft R Client, Machine Learning ServerIf you are new to both R and Machine Learning Server, this tutorial introduces you to 25 (or so) commonly used R functions. In this tutorial, you learn how to load small data sets into R and perform simple computations...
In part one of this tutorial I discussed the use of R code to produce 3d scatterplots. This is a useful way to produce visual results of multi- variate linear regression models. While visual displays using scatterplots is a useful tool when using most datasets it bec...
The function E=f(σ)=b(σ−c) was computed by linear regression analysis (0.99>r2>0.96). The average value of constant b was 13.89±2.01 in control curves of rat trabecular muscles and 13.42±1.98 in curves with 10 mM caffeine and 7.5 mM Ca2+. Likewise, in cat papillary muscles 20...
