fitting
Curve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, possibly subject to constraints. Curve fitting can involve either interpolation, where an exact fit to the data is required, or smoothing, in which a "smooth" function is constructed that approximately fits the data. A related topic is regression analysis, which focuses more on questions of statistical inference such as how much uncertainty is present in a curve that is fit to data observed with random errors. Fitted curves can be used as an aid for data visualization, to infer values of a function where no data are available, and to summarize the relationships among two or more variables. Extrapolation refers to the use of a fitted curve beyond the range of the observed data, and is subject to a degree of uncertainty since it may reflect the method used to construct the curve as much as it reflects the observed data.

Hello. I've attached an image of an old garden tap with a new garden tap replacement, except the thread on the new tap is larger than the existing tap fitting. Is there a reducing nut that can adapt the new tap to the wall fitting or could the new tap handle be used to replace the old handle and...

Hi Guys
I am at the design stage of having a En-Suite built and have an issue that I cannot seem to resolve.

So my question is, have any plumbers on the forum had issues fitting...
Hi,
Hoping that someone could please identify what this leaking fitting is, such that I can explain it to a plumber.
Not sure whether the groove on the top is a location where you can tighten these "fittings", or whether that is best left to a professional to deal with.
Many thanks for any help.
