Programming
Programming
The Art, Science, and Engineering of Programming is a new journal created with the goal of placing the wonderful art of programming in the map of scholarly works. Many academic journals and conferences exist that publish research related to programming, starting with programming languages, software engineering, and expanding to the whole Computer Science field. Yet, many of us feel that, as the field of Computer Science expanded, programming, in itself, has been neglected to a secondary role not worthy of scholarly attention. That is a serious gap, as much of the progress in Computer Science lies on the basis of computer programs, the people who write them, and the concepts and tools available to them to express computational tasks. The Art, Science, and Engineering of Programming aims at closing this gap by focusing primarily on programming: the art itself (programming styles, pearls, models, languages), the emerging science of understanding what works and what doesn’t work in general and in specific contexts, as well as more established engineering and mathematical perspectives. This is an example of and a guide to writing articles for The Art, Science, and Engineering of Programming.

Methods to prevent overfitting and solve ill-posed problems in statistics: Ridge Regression and LASSO
Methods to prevent overfitting and solve ill-posed problems in statistics: Ridge Regression and LASSO
Linear regression is one of the most widely used statistical methods available today. It is used by data analysts and students in almost every discipline. However, for the standard ordinary least squares method, there are several strong assumptions made about data that is often not true in real world data sets. This can cause numerous problems in the least squares model. One of the most common issues is a model overfitting the data. Ridge Regression and LASSO are two methods used to create a better and more accurate model. I will discuss how overfitting arises in least squares models and the reasoning for using Ridge Regression and LASSO include analysis of real world example data and compare these methods with OLS and each other to further infer the benefits and drawbacks of each method.

An Overview of Visualization in Mathematics, Programming and Big Data
An Overview of Visualization in Mathematics, Programming and Big Data
Visualization is a descriptive way to ensure the audience attention and to make people better understand the content of a given topic. Nowadays, in the world of science and technology, visualization has become a necessity. However, it is a huge challenge to visualize varying amounts of data in a static or dynamic form. In this paper we describe the role, value and importance of visualization in maths and science. In particular, we are going to explain in details the benefits and shortages of visualization in three main domains: Mathematics, Programming and Big Data. Moreover, we will show the future challenges of visualization and our perspective how to better approach and face with the recent problems through technical solutions.

Path Integrals an Introduction
Path Integrals an Introduction
Here we discuss the path integral formalism for quantization of fields. The basic idea is reviewed and explained. This is completely based on the book ``Quantum Field Theory A Modern Introduction" by Michio Kaku. For calculation natural system of units is taken.

MODELO LOGIT
MODELO LOGIT
Es posible diseñar modelos en donde la variable dependiente posea característica cualitativas, ese es el caso que analizaremos en el presente trabajo, enfocándonos únicamente en el modelo LOGIT que nos brinda ciertas ventajas en comparación a un modelo lineal de probabilidad, estimada por mínimos cuadrados ordinarios(MCO) para lo cual resaltaremos dichas diferencias. Los modelos de regresión con respuesta cualitativa son modelos de regresión en los cuales la variable dependiente puede ser de naturaleza cualitativa, mientras que las variables independientes pueden ser cualitativas o cuantitativas, o una mezcla de las dos; por ejemplo, si se está estudiando la relación entre ingresos y el pagar o no impuesto de renta, la respuesta o regresada solo puede tomar dos valores (si paga impuesto de renta o no paga dicho impuesto); otros ejemplos en que la regresada es cualitativa son si la familia posee o no vivienda propia, se aprueba o pierde un curso, padece determinada enfermedad o no la padece. La variable cualitativa en estos tipos de modelos no tiene que restringirse simplemente a respuestas de sí o no, la variable respuesta puede tomar más de dos valores, ser tricotómica o politómica, también se establecen modelos en lo que la variable dependiente es de carácter ordinal o de carácter nominal, en donde no hay preestablecido ningún tipo de orden. En este trabajo se analizara el modelo LOGIT en donde la variable dependiente es de carácter binario o dicotómico (sí o no). (Green 2001) Se trata pues de adoptar una formulación no lineal que obligue a que los valores estimados estén entre 0 y 1 ya que, la regresión con una variable binaria dependiente Y modeliza la probabilidad de que Y = 1. La regresión LOGIT utiliza una función de distribución logística, su función de distribución de probabilidad da lugar a probabilidades ente 0 y 1, y presenta un crecimiento no lineal (con mayores incrementos en la parte central).
