Principal Component Analysis Homework Help
Principal component analysis, commonly denoted as PCA, is a dimensionality reduction technique that is generally used to “reduce the dimensionality” or rather, reduce the number of variables in a large set of data. What this method does is that it transforms large sets of variables into smaller ones that contain as much information as possible as the larger ones. Though reducing the dimensionality of a data set makes it easier to manipulate and analyze data, it can make it less accurate.

Time Series Analysis
Time series analysis is the evaluation and interpretation of time series data. It is also known as trend analysis. Time series data is always in a sequence of a distinct interval or period. The data considered for time analysis can be categorized into:
Time series data
A pack of observations made values taken by a variable at different periods or intervals.
This is the data of one variable or more. This data is often gathered at the same point in time.
Pooled data is a mix of both cross-sectional data and time-series data.
Probability Density Function
The probability density function is an expression in math and statistics. It defines the likelihood of an event for a random discrete variable rather than a continuous random variable. A discrete random variable provides the exact value of the variable. When you use a graph to portray the probability density function, the interval where the variable will fall is indicated by the area under the curve. The likelihood of a discrete random variable happening is equal to the total area in this graphical interval.
Cumulative Density Functions
A cumulative density function is a technique used to describe the distribution of a random variable. This method is popular because it is suitable for all types of random variables including continuous, discrete, and mixed. CDF can also be used to compare the likelihood of values occurring under particular conditions.
