I enjoy the simplicity but am annoyed that you can't use certain features without paying a higher price. $80/year is pretty high for a basic subscription.

This web site is quick and easy to use…
This web site is quick and easy to use and their support is amazing. I have used the live chat when I was in the middle of a project and gotten an answer in minutes. It takes a lot of the stress out of the process.I saw a review on another site warning people not to supply a credit card. The fact that this person found their template on a site that did not warn them it was a paid service is not the fault of PFDfiller. When you got to their web site, they immediately let you know that you can sign up and get a free trial period, then ask for your payment information, which is SOP for online services as far as I know and gives you the option not to use the service if you don't want to do so.

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.
What is a PCA procedure?
Principal component analysis (PCA) is a statistical procedure that uses an orthogonal transformation to convert a set of observations of possibly correlated variables (entities each of which takes on various numerical values) into a set of values of linearly uncorrelated variables called principal components.
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.
Why do we do PCA?
PCA is an unsupervised linear dimensionality reduction algorithm to find a more meaningful basis or coordinate system for our data and works based on covariance matrix to find the strongest features if your samples. We do this by reducing the dimension i.e. the features.
How do you explain PCA?
Principal Component Analysis, or PCA, is a dimensionality-reduction method that is often used to reduce the dimensionality of large data sets, by transforming a large set of variables into a smaller one that still contains most of the information in the large set.
Why does PCA maximize variance?
Note that PCA does not actually increase the variance of your data. This enables you to remove those dimensions along which the data is almost flat. This decreases the dimensionality of the data while keeping the variance (or spread) among the points as close to the original as possible.
Can PCA be used for prediction?
PCA is mostly used as a data reduction technique. While building predictive models, you may need to reduce the number of features describing your dataset. It's very useful to reduce this high dimensionality of data through approximation techniques, at which PCA excels.
Does PCA reduce noise?
Principal Component Analysis (PCA) is used to a) Denise and to b) reduce dimensionality. It does not eliminate noise, but it can reduce noise. Basically an orthogonal linear transformation is used to find a projection of all data into k dimensions, whereas these k dimensions are those of the highest variance.
Why do we maximize variance in PCA?
By maximizing variance, you maximize the information that you get out of your data. When we project a data point on the principal component (x axis) we loose some information of that data (the distance between original point and projected point) ~ information loss.
What does variance in PCA mean?
In case of PCA, “variance" means summative variance or multivariate variability or overall variability or total variability. Their variances are on the diagonal, and the sum of the 3 values (3.448) is the overall variability.
How much of the variance is explained by the first principal component?
The 1st principal component accounts for or “explains" 1.651/3.448 = 47.9% of the overall variability; the 2nd one explains 1.220/3.448 = 35.4% of it; the 3rd one explains. 577/3.448 = 16.7% of it. So, what do they mean when they say that “PCA maximizes variance" or "PCA explains maximal variance”?
Why are principal components orthogonal?
The same is done by transforming the variables to a new set of variables, which are known as the principal components (or simply, the PCs) and are orthogonal, ordered such that the retention of variation present in the original variables decreases as we move down in the order.
What does principal component analysis do?
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.
