Mean shape index

Using this index, it is possible to seek backwards in the shapefile by, first, seeking backwards in the shape index (which is possible because it uses fixed-length records), then reading the record offset, and using that offset to seek to the correct position in the .shp file. It is also possible to seek forwards an arbitrary number of records The arithmetic mean is the sum of the elements along the axis divided by the number of elements. Note that for floating-point input, the mean is computed using the same precision the input has. Depending on the input data, this can cause the results to be inaccurate, especially for float32 (see example below). Body mass index (BMI) is a value derived from the mass and height of a person. The BMI is defined as the body mass divided by the square of the body height, and is universally expressed in units of kg/m 2, resulting from mass in kilograms and height in metres.

The index measures mean perimeter-to-area ratio of a legend type. A high value of S1 indicates relatively many patches with small interiors. The second shape  21 Dec 2018 Traditionally, the shape of a three-dimensional (3D) particle is is that the distribution of the AR is considered rather than only the mean value. Knowing your body shape—not just your weight—may be the key to better health. First there was body mass index (BMI), which compares weight with height, but doesn't account for lean muscle mass or bone What Does It Mean for You? This shape index (SHAPE) measures the complexity of patch shape compared to a standard shape (square or almost square) of the same size, and therefore alleviates the size dependency problem of PARA. This shape index is widely applicable in landscape ecological research (Forman and Godron 1986). To overcome the shortfalls of BMI, Nir Y. Krakauer and Jesse C. Krakauer, studied a sample population of 14,105 adults from USA and came up with A Body Shape Index (ABSI) based on waist circumference, BMI and height. They published their journal at plos.org.This ABSI calculator is developed based on the journal. The below details are also based on the journal.

Sharpe Ratio: The Sharpe ratio is the average return earned in excess of the risk-free rate per unit of volatility or total risk. Subtracting the risk-free rate from the mean return, the Figure: The shape index scale ranges from -1 to 1 as shown. The shape index values are encoded as a continuous range of grey-level values between 1 and 255, with grey-level 0 being reserved for background and flat regions (for which the shape index is undefined). The shape index is calculated from the principal curvatures of the Hessian, which is very susceptible to noise. Therefore the plugin asks you to specify a radius for Gaussian blurring as a preprocessing step. Example. With radius 2, this results in the following shape index map (bright spots correspond to caps, dark to cups): Where _Index_ is either an array of shape indexes (integers) or shape names (stings). Since the shape names are not unique (and people i am making this macro for have a nasty habit of having multiple shapes with the same name) i need to rely on the shape index number. My problem is i dont know how to get the index number of a given shape.
