Dummy Variablesand Binary Variables The termsdummy variableand binary variable are sometimes used interchangeably. However, they are not exactly the same thing. A dummy variable is used inregression analysisto
binary variable 是二进制变量的意思。变量一共有11个，所有变量都是二进制的虚拟变量（0和1）。

binarydata A variable containing the binary data to encode. encoding A string that specifies the encoding method to use to represent the data; one of the following: Hex: use the characters 0-9 and A-F to represent the hexadecimal value of each byte; for example, 3A. UU: use the UNIX...
A similar example as withbinary formatshould explain the relation between field specifiers and arguments in case of the binary scan subcommand: binary scan$bytes s3s first second This command (provided the binary string in the variablebytesis long enough) assigns a list of three integers to the...
Binary data types of either fixed length or variable length.Argumentsbinary [ ( n ) ]Fixed-length binary data with a length of n bytes, where n is a value from 1 through 8,000. The storage size is n bytes.varbinary [ ( n | max ) ]...
可变长度编码 Variable-length encoding 固定长度编码对存储空间的占用不灵活,比如一个 int64 类型范围内的值,当值较小时就会产生比较多的 0 字节无效位,直至达到 64 位。使用可变长度编码可限制这种空间浪费。 可变长度整数(以下简称为varint)压缩算法是将整数压缩成比通常需要的更小空间的一种方法。一个varint算法以...

If the input data type is non-BYTE, the number of variable size dimensions is at most 1. If the data type is BYTE, the shape must be [1]. The supported data types can be found here To send a raw binary request, the Inference-Header-Content-Length header must be provided wit...
