De los documentos que hemos podido leer, podemos concluir que R, es un lenguaje de programación que es muy útil dentro del ámbito de la empresa, ya que se puede utilizar en diferentes áreas dentro de una misma empresa, como pueden ser modelos lineales y no lineales, tests estadísticos, análisis de series temporales, algoritmos de clasificación y agrupamiento, etc.Este lenguaje consta también de una buena capacidad gráfica, por lo que se pueden generar gráficos de una alta calidad. R también tiene la ventaja añadida de que es un proyecto de software libre, por lo que tanto las empresas grandes como las pequeñas pueden utilizarlo como mejor les convenga, pudiendo incluso modificarlo para que satisfaga completamente sus necesidades

Time series data are widely seen in analytics. Some examples are stock indexes/prices, currency exchange rates and electrocardiogram (ECG)

-
Time series decomposition is to decompose a time series into trend, seasonal, cyclical and irregular components.

-
Time series clustering is to partition time series data into groups based on similarity or distance, so that time series in the same cluster are similar.

-
o build a classification model based on labelled time series and then use the model to predict the label of unlabelled time series.

To center a variable, simply subtract its mean from each data point and save the result into a new R variable, as demonstrated below.
-
-
we can simply multiply our centered term from step one and save the result into a new R variable, as demonstrated below.
-
-
-
In this case, the quadratic and cubic terms are not statistically significant themselves nor are their models statistically significant beyond the linear model.
-
it can be helpful to summarize and compare our potential models using the summary(MODEL) and anova(MODEL1, MODEL2,… MODELi) functions.
-
-
The regression topics covered in these tutorials can be mixed and matched to create exceedingly complex models.
-
The good news is that more complex models can be created using the same techniques covered here. The basic principles remain the same.
