Explain how error measures can help to optimize moving averages, weighted moving averages, and exponential smoothing methods.

The error measures are Mean Absolute Deviation(MAD), Mean Square Error, Mean Absolute percentage Error (MAPE) . The error measure technique that provides least measure of error is considered as the suitable technique.

Explanation:

Error measures are known as error of observation. It can be random or systematic. The weighted moving averages are done by putting more weight on recent data and less on past data. It is proved by multiplying each price by weighting factor.

The Exponential smoothing technique uses smoothing constant as a predictor for future forecasting. Whenever we use the number as average in forecasting then it is smoothed.

answer: cannibalism, the capac raymi, capacocha, the eight day feast, the combing of the hair

explanation:

the incas have many rituals, cannibalism was always a very ritual thing, which was normally tied to sacrifices, warfare, death, and regeneration.

  the capac raymi was one of the most important ceremonies. it occurred around the summer solstice and was when they worshiped their sun god, also known as inti.

  the capacocho was another one of their most important ceremonies. it was when many children where selected to start their training, and these children where destined to become sacrificial blessings to their sun god, inti. being chosen for this ritual was a blessing.

  the eight day feast was a feast that lasted 8 days and, each day, the day began with a chanting at dawn. a follow up song at noon. which ended with complete silence at the end of the day. on this day, inca royalty was always dressed in silver and gold laced clothing.

  the combing of the hair was the most important ritual to young girls. this ritual was known as the coming of age ceremony, but only the most beautiful girls where chosen. in this ceremony, the girls chose their new name and where chosen as either brides, or princesses of rulers.
