Seemless interaction so far, good online support.
The company does not yet have the CA Residential Purchase Agreement and Escrow Instructions (effective 11/26/14) available, my only knock. May not be released yet to public as a non-draft document. Ralph 12/13/14

Great product, have not really used much but I got it in anticipation of a pdf filler. Plus the price is great. My son is really happy we have it makes his applications look amazing.

I'm impressed with PDFfiller but I think there could be more options of background colours of the textbox, including different shades within each color.

So far it has been frustrating ( just because I am not tech savvy) I am just trying to reprint a pay stub that I have lost from a former employer and I just keep running into problems. However after watching a video I figured it out without a problem. Customer service is A1.

Love the software but a bit of a brain surgery to start with each new document. The links, steps and path for loading and working on documents need to be highlighted better for new users. Probably makes great sense to the programmer but new users have to hunt for the next link or button to click.

Great customer experience with this company. Very responsive to technical questions and billing service cared more about our satisfaction than most companies even though it wasn't to their direct bottom line advantage. Will use them again surely.

First-class customer service! I wanted to try out the free trial version but ended signing up for an annual subscription. I contacted the customer service about this error, and they gave me the refund immediately.

When should I standardize my data?
Standardization: Standardizing the features around the center and 0 with a standard deviation of 1 is important when we compare measurements that have different units. Variables that are measured at different scales do not contribute equally to the analysis and might end up creating a basis.

Why do we need to standardize data?
Data standardization is about making sure that data is internally consistent. That is, each data type has the same content and format. Standardized values are useful for tracking data that isn't easy to compare otherwise. For example, suppose you and your friend went to different universities.
What does it mean to standardize data?
In statistics, standardization is the process of putting different variables on the same scale. This process allows you to compare scores between different types of variables. For instance, a standardized value of 2 indicates that the observation falls 2 standard deviations above the mean.
Should you standardize data before applying PCA?
Yes, it is necessary to normalize data before performing PCA. The PCA calculates a new projection of your data set. If you normalize your data, all variables have the same standard deviation, thus all variables have the same weight and your PCA calculates relevant axis.
What does standardize the data mean?
In statistics, standardization is the process of putting different variables on the same scale. This process allows you to compare scores between different types of variables. Typically, to standardize variables, you calculate the mean and standard deviation for a variable.
What is data standardization?
Data standardization is the critical process of bringing data into a common format that allows for collaborative research, large-scale analytics, and sharing of sophisticated tools and methodologies.
