I had a problem with a pdf file freezing up on deadline and not being able to copy it when I was on deadline. I have to say, though, your online customer service was extremely helpful in solving my problem.

I was in a jam! Law School needed me to fill out three documents and sign them and return. The only problem was that I did't have a fax, or scanner. With PDF filler I accomplished my mission at a fraction of the time and cost.

How do you perform a PCA?
Take the whole dataset consisting of d+1 dimensions and ignore the labels such that our new dataset becomes d dimensional.
Compute the mean for every dimension of the whole dataset.
Compute the covariance matrix of the whole dataset.
Compute eigenvectors and the corresponding eigenvalues.

What is PCA and how does it work?
The main idea of principal component analysis (PCA) is to reduce the dimensionality of a data set consisting of many variables correlated with each other, either heavily or lightly, while retaining the variation present in the dataset, up to the maximum extent.
When should I use PCA?
PCA should be used mainly for variables which are strongly correlated. If the relationship is weak between variables, PCA does not work well to reduce data. Refer to the correlation matrix to determine. In general, if most of the correlation coefficients are smaller than 0.3, PCA will not help.
What is PCA in simple terms?
Principal Components Analysis (PCA) is a technique that finds underlying variables (known as principal components) that best differentiate your data points. Principal components are dimensions along which your data points are most spread out: A principal component can be expressed by one or more existing variables.
Why do we do PCA?
PCA is a method used to reduce number of variables in your data by extracting important one from a large pool. It reduces the dimension of your data with the aim of retaining as much information as possible.
What is the purpose of PCA?
PCA is mostly used as a tool in exploratory data analysis and for making predictive models. PCA is the simplest of the true eigenvector-based multivariate analyses. Often, its operation can be thought of as revealing the internal structure of the data in a way that best explains the variance in the data.
