The outputs of the system are great ... just your opening page is a bit confusing. I just wanted to look convert a document but couldn't see conversion icons - finally worked out that I have to use Add New button - remember people are coming to your website from other portals they have used before - and like me they look for a document conversion tool!

Awesome software!
Very easy to use and great to help fill PDF's and create them. I use this software very often and I rarely have issues.
Sometimes it lags and it can be a pain, but overall this is a great software to use and I don't have many cons.

Best Service :)
Thank you so much for such good hospitality. Most companies would not offer a refund so easily for an automatic subscription and so fast as well. This shows such good ethics as a company. I really appreciate that! As well if I ever did have the need to use this service, makes me happy to come back and also recommend it to others!

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.
Should I standardize before PCA?
Hello ! Yes, it is necessary to normalize data before performing PCA. The PCA calculates a new projection of your data set. And the new axis are based on the standard deviation of your variables.
Why do we standardize data for PCA?
2 Answers. Normalization is important in PCA since it is a variance maximizing exercise. It projects your original data onto directions which maximize the variance. The first plot below shows the amount of total variance explained in the different principal components her we have not normalized the data.
Do you need to standardize data for PCA?
Yes, it is necessary to normalize data before performing PCA. 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.
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 is the goal of PCA?
PCA is a widely used statistical tool for dimension reduction. The objective of PCA is to find common factors, the so called principal components, in form of linear combinations of the variables under investigation, and to rank them according to their importance.
How do you standardize data?
Subtract mean and divide by standard deviation: Center the data and change the units to standard deviations. Subtract mean: Center the data. Divide by standard deviation: Standardize the scale for each variable that you specify, so that you can compare them on a similar scale.
What type of data should be used for PCA?
PCA works best on data set having 3 or higher dimensions. Because, with higher dimensions, it becomes increasingly difficult to make interpretations from the resultant cloud of data. PCA is applied on a data set with numeric variables.
