comment How can I keep the form of the expression when I use `TeXForm[HoldForm[]]`?
Look at FullForm[HoldForm[your expression]]. Mathematica does not have a Divide operator, so there is no difference between the representation of x/y and that of x y^-1. You would need to process the expression as a string to accomplish what you desire.

comment Why does this expression involving HypergeometricU and $MinPrecision crash?
It seems fine in 11.0. Has anyone else tested it beyond 10.4?

comment `DateListPlot`: not a valid dataset or list of datasets?
It appears as if the key is of the form "a__dd__" DateListPlot will fail. i.e. any alpha sequence followed by at least two digits.

i.e. something equivalent to the function lm() in R

comment Epilog not working
@Wyatt. The code in the solution above works fine giving 0.5 E^(-0.125 x) (2.64575 sin(0.992157 x)+1. cos(0.992157 x)) and y1[0]=0.5; Please edit your question to show the changed function.
