Statistics and Data with R

Menukar nilai dua buah variabel

Thu Jun 11, 2009 8:28 am by dimas

Biasanya untuk menukar dua nilai variabel, kita menggunakan variabel bantu.
contoh : Menukar A=5 dan B=3.
Penyelesaian :
C=A=5;
A=B=3;
B=C=5;

Ternyata kita juga dapat menukar dua nilai variabel tanpa menggunakan variabel bantu. Ada beberapa cara, diantaranya menggunakan operator + dan -.
Contoh : Menukar A=5 dan B=3
Penyelesaian :
A=A+B=5+3=8;
B=A-B=8-3=5;
A=A-B=8-5=3;

Nah, …

Matematika Asyik...

Tue Jun 09, 2009 6:50 pm by vahn

Asyiknya Matematika!
Banyak anak "alergi" matematika. Ada lho, cara memperkenalkan matematika pada balita secara menyenangkan.

Mengapa ya, banyak anak "takut" pada matematika? Padahal, jika mereka menguasainya dengan baik, mata pelajaran ini bisa sangat fun, lho. Saat ini, mulai banyak orangtua memperkenalkan matematika sejak dini kepada putera-puterinya. Mereka berharap, …

Menghitung nilai pendekatan phi

Fri Jun 05, 2009 6:50 pm by vahn

Salah satu nilai pendekatan phi (π) yang sering dipakai adalah 22/7 atau 3,14.
Pada abad ke-5 ahli astronomi China telah menemukan pendekatan sampai enam tempat desimal yaitu 355/113.
Pada tahun 1737, rasio keliling lingkaran terhadap diameternya diberi nama "π" (dibaca "phi") oleh Leonard Euler, seorang matematikawan terkenal asal Swiss (Wahyudin, 2004: 159).

Statistics and Data with R

Post  vahn on Tue Jun 09, 2009 6:57 pm

R, an Open Source software, has become the de facto statistical computing environment. It has an excellent collection of data manipulation and graphics capabilities. It is extensible and comes with a large number of packages that allow statistical analysis at all levels – from simple to advanced – and in numerous fields including Medicine, Genetics, Biology, Environmental Sciences, Geology, Social Sciences and much more. The software is maintained and developed by academicians and professionals and as such, is continuously evolving and up to date. Statistics and Data with R presents an accessible guide to data manipulations, statistical analysis and graphics using R.

Assuming no previous knowledge of statistics or R, the book includes:

* A comprehensive introduction to the R language.
* An integrated approach to importing and preparing data for analysis, exploring and analyzing the data, and presenting results.
* Over 300 examples, including detailed explanations of the R scripts used throughout.
* Over 100 moderately large data sets from disciplines ranging from Biology, Ecology and Environmental Science to Medicine, Law, Military and Social Sciences.
* A parallel discussion of analyses with the normal density, proportions (binomial), counts (Poisson) and bootstrap methods.
* Two extensive indexes that include references to every R function (and its arguments and packages used in the book) and to every introduced concept.

An accompanying Wiki website, http://turtle.gis.umn.edu includes all the scripts and data used in the book. The website also features a solutions manual, providing answers to all of the exercises presented in the book. Visitors are invited to download/upload data and scripts and share comments, suggestions and questions with other visitors. Students, researchers and practitioners will find this to be both a valuable learning resource in statistics and R and an excellent reference book.
