Respuesta :
a stock has a correlation with the market of 0.61. the standard deviation of the market is 30%, and the standard deviation of the stock is 31%. the stock's beta is 0.63.
In arithmetic and data, the deviation is a measure of the difference between the observed fee of a variable and a few other costs, often that variables suggest. The signal of the deviation reports the route of that difference (the deviation is high-quality whilst the determined cost exceeds the reference value). The importance of the value indicates the scale of the distinction. A deviation that may be a distinction between a found fee and the true price of an amount hobby (where genuine price denotes the anticipated cost, along with the population mean) is an error. A deviation that is the distinction between the determined value and an estimate of the real cost (e.G. The sample suggest; the expected value of a pattern can be used as an estimate of the anticipated price of the population) is a residual. These ideas are relevant to facts in the c programming language and ratio tiers of dimension.
