With the exception of the scam you have going to get people to sign up for your service... (i.e., On a holiday I came into my office to get work done quickly so I could then spend time with my family. I was soo pleased with your service as it let me upload a document and seamlessly edit it for 2 hours and the peace of mind that everything was working properly as your program continually provided feedback saying that 'all changes have been saved'. Then when I finally finished, after triple checking my work and feeling thrilled that I could go celebrate the holiday and be with my family, I selected the big bright button that says, Done!. And only THEN, after 2 hours of work, did you tell me, there is an error and I need to sign up for your program. You should be ashamed of yourselves. I was so excited to tell other people about your program and how well it works. After being scammed, ripped off in terms of money and precious time, I won't be telling anyone about your service. If you prefer to keep me as a happy customer, perhaps you will find a way to make up for this inconvenience (e.g., give me a discounted membership, upgrade my membership, some other kind gesture?) and correct this misunderstanding that you are covertly enticing people to use your program with an inconsiderate scam. I'd love if you followed up with me about this survey. Thank you. Sarah

I think your site is well designed and has substantial potential. But being unfamiliar with all the choices, my initial effort at using your site took a little longer that I had hoped it would. But that is a minor critique. i'll do more exploring at a later date.

Initially
Initially, it was a bit difficult to insert the text; but after a while I discovered the "T" tool for aligning texts. I also like the fact that I had choices for signatures.

Little Confusing
It was a little bit confusing as my computer skills have deteriorated due my age and also effects of a stroke. Otherwise I was able to manage to obtain what I needed.

Statues: Principal Component Analysis (PCA), Step-by-Step
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.
What are the components in PCA?
The principal components are the eigenvectors of a covariance matrix, and hence they are orthogonal. Importantly, the dataset on which PCA technique is to be used must be scaled. The results are also sensitive to the relative scaling. As a layman, it is a method of summarizing data.
What is PCA used for?
Principal component analysis (PCA) is a technique used to emphasize variation and bring out strong patterns in a dataset. It's often used to make data easy to explore and visualize.
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.
