I am older and my hand shakes so badly I cannot fill in forms -- it is a real life-saver, not to mention time-saver. I don't have to call someone in to fill the forms out for me, I've already recommended PDFfiller to a dozen friends!

It was wonderful using the form to fill in my information, however, I was shocked to learn at the end that I am required to joint for a fee or my document would be unprintable. You should notify a person first there is a fee in case they have no money to pay your fee or do not wish to pay when you can print these forms out from many sources and fill in by using a pen.

The log transformation can be used to make highly skewed distributions less skewed. This can be valuable both for making patterns in the data more interpretable and for helping to meet the assumptions of inferential statistics. Figure 1 shows an example of how a log transformation can make patterns more visible.
Log transformation The value 1 is added to each of the pixel value of the input image because if there is a pixel intensity of 0 in the image, then log (0) is equal to infinity. During log transformation, the dark pixels in an image are expanded as compare to the higher pixel values.

The log transformation is, arguably, the most popular among the different types of transformations used to transform skewed data to approximately conform to normality. If the original data follows a log-normal distribution or approximately so, then the log-transformed data follows a normal or near normal distribution.
Log Transformations. The log transformation can be used to make highly skewed distributions less skewed. This can be valuable both for making patterns in the data more interpretable and for helping to meet the assumptions of inferential statistics.
Only the dependent/response variable is log-transformed. Exponential the coefficient, subtract one from this number, and multiply by 100. Only independent/predictor variable(s) is log-transformed. Both dependent/response variable and independent/predictor variable(s) are log-transformed.
Transforming data is a method of changing the distribution by applying a mathematical function to each participant's data value. For example, if your data looks like the top example, take everyone's value for that variable and apply a square root (i.e., raise the variable to the ½ power).
A typical use of a logarithmic transformation variable is to pull outlying data from a positively skewed distribution closer to the bulk of the data in a quest to have the variable be normally distributed.
