Independent variable that is a distribution?

Hi,

I am attempting a logistic regression analysis with a binary response and explanatory variables measured at the individual level and also some measured within subgroups of the observations (nests). For each nest containing individual observations I know the distribution of income in the form of a histogram (but not the individual incomes). I could enter each histogram value as a separate variable (i.e. percent in class 1) but I would rather fit a distribution to each histogram for each nest. Then, similar to a regression with random effects (but in a sense the diametric opposite), a parameter estimate would be assigned to this variable. Analogous to integration over multiple versions of the random effect to find the one which maximizes likelihood, this would integrate over each known distribution for each nest when estimating the parameter estimate attached to it and other independent variables. I am wanting to do this because I believe that income interacts with the relationships between other independent variables and my dependent variable but do not know the actual income, only the distribution over a subset of observations. In doing so, I'm wanting to partially overcome what is called the ecological fallacy. Is this approach a known method? I have not run across it. It seems more computationally intensive than the random effects model as you would have to estimate all parameters in the model and by integration over the pre-specified distributions for each nest. At least the distribution will not also have to be estimated as well. Any food for thought on other ways to overcome the ecological fallacy (correlation)? Thanks. -Seth

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
Thread 'Imaginary Pythagorus'
I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
