अपने प्रश्न का उत्तर देने के लिए: नहीं, आप लघुगणक के लिए एक सामान्य निश्चित अंकन नहीं मान सकते हैं।
log10
lnएक्स (लगभग) स्वाभाविक रूप से प्राकृतिक लघुगणक को दर्शाता है
लॉगइएक्स (लैटिन: लॉगरिथमस नेचुरलिस), या बेस में लॉगरिथम इ। संकेतनलॉगएक्स should be the adopted notation for the natural
logarithm, and it is so in mathematics. However, it often represents
the "most natural" depending on the field: I learned it as the
base-∗10 logarithm (log10) at school, and it is often used
this way in engineering (for instance in the definition of decibels)
Quite often, if you are not concerned with the meaning of physical units (like decibels @Matt Krause), nor interested in specific rates of change (in biostatistics, the log-ratio for fold-change often denotes the base-2 logarithm log2), it is likely that the natural logarithm (loge) is used.
For instance, in power or Box-Cox transforms (for variance stabilization), the natural logarithm appears as a limit when the exponent tends to 0.
Going back to your initial motivation, the Good-Turing Frequency Estimation, it is interesting to read The Population Frequencies of Species and the Estimation of Population Parameters, I. J. Good, Biometrika, 1953. Here, he used logarithmms in different contexts: variable transformation for variance stabilisation (mentioning Bartlett and Anscombe), sum of harmonic series, entropy. We see that he generally uses log as the natural logarithm, and once in a while in the paper specifies loge or log10, when the context requires it. For variance stabilization, or basic entropy estimation, a factor on the logarithm does not change much the result, as the outcome allows a linear change.
ln
माना जाता है। हालाँकि, दोनों संबंधित हैं:log(x) = ln(x) / ln(10) = ln(x) / 2.303
और ln -likelihood फ़ंक्शन log10 -likelihood फ़ंक्शन के समान बिंदु पर चरम पर पहुंचता है ।
