In VGAM: Vector Generalized Linear and Additive Models

Melbourne Daily Maximum Temperatures

Description

Melbourne daily maximum temperatures in degrees Celsius over the ten-year period 1981–1990.

Usage

data(melbmaxtemp)

Format

A vector with 3650 observations.

Details

This is a time series data from Melbourne, Australia. It is commonly used to give a difficult quantile regression problem since the data is bimodal. That is, a hot day is likely to be followed by either an equally hot day or one much cooler. However, an independence assumption is typically made.
