After discovering that TurboTax does not have a Mac version for business tax returns, I found PDFfiller and it is a great alternative. It is much more reasonable and includes all the forms needed to file my return.

Really good, not sure how I would be at editing large amounts of info on a PDF with the website but I could be surprised if I went through the online training.

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.

What is column standardization?
Geometrically, column standardization means squishing the data points such that the mean vector comes at origin and the variance(by either squishing or expanding) on any axes would be 1 in the transformed space. Column standardization is often called mean centering and variance scaling(squishing/expanding).
What do you mean by standardization?
Standardization is the process of developing, promoting and possibly mandating standards-based and compatible technologies and processes within a given industry. Standards for technologies can mandate the quality and consistency of technologies and ensure their compatibility, interoperability and safety.
What is standardization with example?
From a business standpoint, standardization refers to the practice of maintaining some level of consistency in the product or service that a company provides. A company wants to produce a consistent product, so consumers will know what they're buying. Say, for instance, a bakery produces loaves of wheat bread.
What is the purpose of standardization?
Standardization is the process of determining the exact concentration (molarity) of a solution. Titration is one type of analytical procedure often used in standardization. In a titration, an exact volume of one substance is reacted with a known amount of another substance.
What is standardization in research?
Standardization refers to methods used in gathering and treating subjects for a specific study. In order to compare the results of one group to the results of a second group, we must assure that each group receives the same opportunities to succeed. Standardization of the research methods is often a lengthy process.
What is the difference between normalization and standardization?
The terms normalization and standardization are sometimes used interchangeably, but they usually refer to different things. Normalization usually means to scale a variable to have a value between 0 and 1, while standardization transforms data to have a mean of zero and a standard deviation of 1.
Why do we standardize or normalize 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.
What is normalization and standardization in machine learning?
In statistics, Standardization is the subtraction of the mean and then dividing by its standard deviation. In Algebra, Normalization is the process of dividing of a vector by its length, and it transforms your data into a range between 0 and 1. Originally published at https://www.safacreations.net.
