Density Plot Multiple density plots Multiple density plots using facets Stacked density plot Pooling histogram and density plots Density Plot A density plot is a representation of the distribution of a continuous variable.

Box Plot Grouped box plot Notched box plot Box plot with continuos variable Box plot with computation Box Plot It is used to know the distribution of the continuous variable vary with the levels of the categorical data.

Introduction Histogram Histogram with normal density curve Frequency polygon Comparison of distribution Introduction Histogram and frequency polygon are very useful graphics to have an idea about the distribution of a continuous variable.

Bar chart Stacked bar chart Note Bar chart A bar chart is used to present categorical data with rectangular bars. In a bar chart, the height of the rectangular bars is proportional to the number of cases in each group.

An Overview One of the most important and challenging problems in time series modeling is to correctly forecast a particular time series by observing its distribution. This behavior of time series arises urgent need of developing generalized time series models for a particular statistical distribution.

An Overview Parametric inference is the process by which information from sample data is used to draw conclusions about the population properties from which the sample was selected. The distribution of the population from which sample is drawn is assumed to be known and can be modeled by a probability distribution that have a fixed set of parameters.

An Overview Statistical computing can be broadly described as computational, graphical, and numerical approaches to solving statistical problems. It deals with numerical methods and algorithms, such as optimization and random number generation.

Introduction Components of Time Series Long-Term Trend Short-Term Fluctuations Random/Irreguar Movements Introduction A set of ordered data points taken at successive intervals in time is known as time series.

The R environment R is an integrated suite of software facilites for data manipulation, calculation and graphical display.
Among other things it has
an effective data handling and storage facility a suite of operators for calculations on arrays, in particular matrices a large, coherent, integrated collection of intermediate tools for data analysis graphical facilities for data analysis and display either directly at the computer or on hardcopy a well developed, simple and effective programming language (called ‘S’) which includes conditionals, loops, user defined recursive functions and input and output facilities.
