allow for time-invariant and time-variant covariates, but the latter require stronger assumptions in terms of exogeneity. The discrete-time hazard function...

and random field is a random function on any set (typically time, space, or a discrete set). If a random variable X : Ω → R {\displaystyle X\colon \Omega...

transform maps a function having a discrete time domain into one having a discrete frequency domain. The discrete-time Fourier transform, on the other hand...

presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent. The bars can be plotted vertically...

transient, if formed by a discrete explosion, or sustained, if produced by a continuous eruption or closely spaced discrete explosions. The solid and...

taken at successive equally spaced points in time. Thus it is a sequence of discrete-time data. Examples of time series are heights of ocean tides, counts...

instants in the case of discrete time. An oscilloscope is a tool commonly used to visualize real-world signals in the time domain. A time-domain graph shows...

adjusted for covariates; parametric survival models and the Cox proportional hazards model may be useful to estimate covariate-adjusted survival. The...

Discrete wavelet transform (continuous in time) of a discrete-time (sampled) signal by using discrete-time filterbanks of dyadic (octave band) configuration...

of the proportional hazards model: using a restriction on the hazard function, the likelihood does not contain the shape of the hazard over time. The likelihood...

Autocorrelation, sometimes known as serial correlation in the discrete time case, is the correlation of a signal with a delayed copy of itself as a function...
