Most of this package consists of data sets from the
textbook Introduction
to Linear Regression Analysis (3rd ed), by Montgomery, Peck
and Vining.
Some additional data sets and functions related to visualization
of linear and nonparametric regression results are included.

Calculations of One Discrete Model in Several Time Steps
knitr, rmarkdown, matrixcalc, markovchain, matlib
A matrix discrete model having the form
'M[i+1] = (I + Q)*M[i]'.
The calculation of the values of 'M[i]' only for
pre-selected values of 'i'. The method of calculation
is presented in the vignette 'Fundament' ('Base'). Maybe it`s own
idea of the author of the package. A weakness is that the method
gives information only in selected steps of the process.
It mainly refers to cases with matrices that are not Markov chain.
If 'Q' is Markov transition matrix, then MUPkL() may be
used to calculate the steady-state distribution 'p' for
'p = Q*p'.
Matrix power of non integer (matrix.powerni()) gives
the same results as a mpower() from package 'matlib'.
