Just starting to use this - think it will work for me. Sometimes find it awkward to intuit what to do, so would really benefit from a webinar if offered free.

Best PDF Editor
Up until a few years ago, all PDF software seemed the same to me. 'What could they do that much better to make a difference' was a question I asked. PDFfiller answered the question the first time I got to use it.
PDFfiller is the perfect PDF editing and managing software that I have tried by a mile. Modifying documents and making last minute changes has never been easier. Smart signature protection, revision history, and commenting are just a few of the great features that make PDFfiller my favorite.
Loved it since the first time I got to use it. Well worth the price.

So much better than acrobat
This is really good tech and works much better than acrobat! I was shocked that people were leaving negative reviews - then found out they all complain that you have to sign up after editing your document - SO WHAT you cannot expect amazing tech for free. I don’t get why people complain. Tech is amazing customer service is second to none.

It's great
It's great. Not as good as adobe in the areas of text replacement or image addition. It is also not as sophisticated for selection mechanisms. If you need to fill in documents or create PDFs this is a solid application that can do the stuff that you will need quickly and cheaply.

I used this one time for squares for a fundraiser and was looking forward to continuing using this service needed for a side job; however, this side job fell through. I thought I had cancelled on March 2, but must have not submitted something. I was charged today. If I could be refunded I would really appreciate it.

Why do we log time series data?
For forecasting and economic analysis many variables are used in logarithms (logs). In time series analysis, this transformation is often considered stabilizing the variance of a series. Using logs can be damaging for the forecast precision if a stable variance is not achieved.
Why do we take log of data?
There are two main reasons to use logarithmic scales in charts and graphs. The first is to respond to skewness towards large values. i.e., cases in which one or a few points are much larger than the bulk of the data. The second is to show percent change or multiplicative factors.
Why do we apply log transformation?
Using the log transformation to make data 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. In this case, the log-transformation does remove or reduce skewness.
How do you interpret log transformed data?
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.
What does a log transformation do?
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.
How do you back transform log data?
For the log transformation, you would back-transform by raising 10 to the power of your number. For example, the log transformed data above has a mean of 1.044 and a 95% confidence interval of ±0.344 log-transformed fish. The back-transformed mean would be 101.044=11.1 fish.
When should you log transform data?
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.
hey guys my name is Madison don't and I am a science grad bio teacher and a tripathi student about three months ago I went off the pill and because I didn't have the little lines anymore to remind me when my period was coming I really needed to get a good tracking app so in the past I've tried quite a few and I did download all of the tracking apps available on the App Store that looked decent when I did first come off the pill just to make sure that I was getting the best one but in the past I've really just downloaded it tried it for a month and then yeah it's either been too hard or it just wasn't what I really needed and so I would always end up deleting it but I've definitely found the perfect one now and it is mostly because it has a notes section so it really allows you to track pretty much anything you want so I might also write in there like you're not just pressing the mood and being like oh I'm sad today but you can actually write like why you're sad and also if I have breakouts or if I have a particular food and it makes me feel sick so like in tolerances you can just kind of keep it all to one area but it does also have some really awesome features to track your symptoms that I will show you in a second so we're going to jump over to the bed there's a little bit more comfy ER and I will show you through the app so if I just open it up so straightaway it tells me how many days left until my next period this is based off the ones that I've previously tracked so first off let's go down the bottom to where it says log charts and then I'll show you the calendar so you can see here that my period was May the 20th and that was a 46 day cycle now when they count your cycle they count the days of your period so the first day of your cycle is the first day of your period so I think that period was probably like six days long I think you can actually check it I was five days long so between the periods it was actually like 41 days after I stopped at that period until I got the next one and so then my next one was 52 days cycle and this one's expecting to be like the averages of those so of course it should probably get more regular as I am longer off the pill so now let's go back home and let's go to calendar so here's the calendar what you can actually do to customize it so let's just say that I was writing notes for today I go in and here you can type whatever you want and that really helps because it can also attract other things as well so for example I started to track my acne on here and when I would break out and when I would have dairy like a cheap dairy day which regrets and all the things like that so it kind of allows you to keep it all in one place and you can go to lifestyle I don't really use this stuff too much but if you want to try and track your fertility and stuff through temperature it allows you to do that and symptoms so this is a really awesome section and you can use the symptoms that they've created for you...
