My dataset consists of hourly values by weekday across several sites, where the sites vary by spatial location and by other common characteristics, such as type, or 'cafe,' 'restaurant,' and 'bar.'
For some sites I am missing days of hourly data. I would like to develop an estimate for mean and variance for the missing hours from the hourly data I do have.
What statistical models / approaches might I use to estimate the mean and variance for a missing hourly at a given site for a given day of the week, where the value is missing in my dataset?
I'm closing this question.
I had been seeking a methodology for developing estimators for hourly values at sites where location and site type were likely to explain a given site's hourly values. I guess that is imputation, but I think, rather, I am looking for some form of regression where the modeling would traverse hourly values across week days and across sites spatially.
In the end, I find my quest for seeking better definition of this modeling challenge a poor fit for this forum.
