Forecast Checks

• header must only include location, target, type, quantile, value (required for zoltpy) and forecast_date, target_end_date

• each row must have the same number of columns as header

• location must be in "locations" column of locations.csv

• target must be in

  paste(1:20,  "wk ahead inc death")
  paste(1:20,  "wk ahead cum death")
  paste(0:130, "day ahead inc hosp")
  paste(1:8, "wk ahead inc case")

  county locations should have only "case" targets

• forecast_date and target_end_date must be in YYYY-MM-DD format

• quantile must be in

  c(0.01, 0.025, seq(0.05, 0.95, by = 0.05), 0.975, 0.99)

• quantile for "case" targets must be in

  c(0.025, 0.100, 0.250, 0.500, 0.750, 0.900, 0.975)

• checks quantile must be an int or float in [0, 1]

• checks value must be an int or float and non-negative

• validates date alignment as documented in the issue add additional validations

• validates quantiles and values (i.e,. at the prediction level):

  • checks that entries in value must be non-decreasing as quantiles increase
  • checks that elements in the quantile are unique

• validates quantiles as a group:

  • there must be exactly one point prediction for each location/target pair
