Tīmeklis2024. gada 1. jūl. · 1. Knowing the formula to calculate the odds ratio will tell you why you get an 'Inf' value. Basically, you're dividing by 0. There's a lot of documentation available on the net ( here you can find an example). As to adding 0.5 to all values, the R implementation of the Fisher's Test only works with nonnegative integers. TīmeklisNoise figure (NF) is the increase in noise power of a device from the input to the output that is greater than the signal gain. In effect, it is the amount of decrease of the signal …

TīmeklisNoise factor of a network is defined as the ratio of signal-to-noise ratio (SNR) at the input to the SNR at the output. (7) Where SNRi is the signal-to-noise ratio at the input of the network and SNRo is the signal-to-noise ratio at the output of the network.
