1. ### Analysing pre- and post-treatment lactate curves

Good morning all, Has anyone got experience with analysing lactate against power curves? I have pre- and post-treatment lactate curves for 10 trialists, which I am hoping to quantifiably analyse. I understand the benefits of such a curve moving down and to the left, but can I establish the...
2. ### Probability on a normal curve

Hey all - It's been a long time since I was in school looking at probability and statistics. i have a bit of a difficult question for me. I have two sets of data: Data Set A has a Mean of 7.9 and a standard deviation of 0.79. The other set of Data, Set B, has a mean of 10.1 and a STD Dev of...
3. ### Which test to compare two curves

I have used a stimulus (stimulus1) in a perception test, to see if the participants perceive it as A or B in a forced choice task. (the stimulus is composed of several features f1,f2...) Then I have changed one of the features (f1) of stimulus1 gradually in 5 different levels. All...
4. ### Stata Graph

Morning, I am using stata for doing graph with command : "twoway line variable1 variable2 timeVariable" In my database, i have a lot of countries and, when stata do this graph for all the countries, the first point of every curve is joined to the last point of this same curve. Here you...
5. ### Multiplying curves

Hi there! I want to multiply multiple curves (density distributions, with area under curve = 1). For each curve, I have the x and y values, but x is identical in each curve. All y values are < 1 and close to zero. Thus, when multiplying the values, eventually, I reach zero. Therefore my...
