A trend is a general direction in which something is developing or changing. It can be relevant to the financial market, social media, fashion, etc.
Trend estimation is a statistical technique to aid interpretation of data. When a series of measurements of a process are treated as a time series, trend estimation can be used to make and justify statements about tendencies in the data, by relating the measurements to the times at which they occurred. This model can then be used to describe the behavior of the observed data.
In statistics, trend analysis often refers to techniques for extracting an underlying pattern of behavior in a time series which would otherwise be partly or nearly completely hidden by noise. If the trend can be assumed to be linear, trend analysis can be undertaken within a formal regression analysis, as described in Trend estimation.
A market trend is a perceived tendency of financial markets to move in a particular direction over time.
In regard to the fashion industry, a fashion trend refers to the clothing, footwear or accessories that are popular at a particular point in time. Fashion is a distinctive and often constant trend in the style in which people present themselves.
Trend forecasting is the process of making predictions of the future based on past and present data and analysis of trends.
Who dictates fashion trends?
Popular fashion designers often mistakenly think that they create trends when they develop their collections. However, that is a bit egotistical. They design & develop clothing that they believe is trend worthy. However, the consumer ultimately decides the acceptance and longevity of a particular trend.
