Oh, sorry, didn't mean to barge in. Yours is way more elaborate, for sure!

So I believe that predictive value requires some coding? Or is there a function ready made for it in excel?

Hello StatDad. Where did you get this equation from, and what is y_hat ? thank you!

If I have a slope for which I do simple linear regression analysis, but each of the 6 datapoints of the slope have their individual (non-equal) standard deviations, how can I calculate the maximum and minimum slope of the graph? One idea we too up was to increase the first half of the data...

Thanks for your reply. Thant might be it. I also thought that one output is the outer blanket, and the other the internal structure, but outer or inner surface would have the same characteristics, no? Anyways, your explanation might explain why they don't correlate linearly, but with...

Since electronic structure is related to magnetism, conductivity, and oxidation (exchange of electrons) they are all related. I recommend you to read Per Kofstad's "High temperature Corrosion", and see if you still have some questions afterward.

Hello MSl, was this of use to you?

What is the difference between fractal dimension determined by surface profilometry and Hg porosimetry? For example, for a given dataset, say samples 1-5, the backbone fractal dimension determined by Hg porosimetry increases from 2.5 to 3 (the percolation fractality is 3 for all samples). For...

anybody? :smile:

One of the outputs of mercury porosimetry is Differential intrusion in ml/g/um. this is ml of Hg per g of sample per um of what? What is that micrometer? The characteristic length of the sample, the average pore diameter or radius?. Also, why is there a "log differential intrusion", for...

pressure range is probably insufficient to cover macropores (I assume you use the standard macro = >0.05um?). The problem is that at some point the Hg just kinda flows into the pores without resistance. Then, the measurement becomes unreliable. the max. pore size it gives as an output is 130um...

Oh, you're working on biomembranes and ion selective ionophores? These might be of interest to you: http://dx.doi.org/10.1016/j.bioelechem.2006.05.009 http://dx.doi.org/10.1002%2Fjcp.20476

anyone kindly has an idea?
