co-channel interference is a major factor in limiting the capacity and link quality in cellular communications. as the co-channel interference is modeled by lognormal distribution, sum of the co-channel interferences of neighboring cells is represented by the sum of lognormal random variables (rvs) which has no closed-form expression. assuming independent, identically distributed (iid) rvs, the...

this study attempts to find if better performance in power play leads a team to victory in a twenty20 match. based on the methodology devised to do so, the study tries to measure the performance of both the teams during power play overs in terms of batting and bowling. the developed measure is called ‘prod’ which is a product of the difference of batting and bowling performance of the teams dur...

This paper examines the hypothesis that short run changes in tne U.S. size distribution of personal income have been systematically related to aggregate levels of output~ personal income~ and employment during the posh7ar period. Part one proposes a procedure for describing the size distribution of income. The observed distribution is approximated by a displaced lognormal distribution vmich cor...

Four sets of experimental data were investigated in terms of normal distribution and presence of outliers. The following sets of compound were investigated: blood-brain barrier partitioning (n=105), inhibitory activity of para-substituted aromatic sulfonamides (n=47), inhibition activity of taxoids (n=63), and estrogen receptor binding affinity of triphenilacrylonitriles (n=25). The normality o...

Let be Y = (Y1, ..., Yn) and X = (X1, ..., Xn) series of pair observations and the objective be finding of a function f(x; a1, ..., am) for which Ŷ = f(X) is the best possible solution of the approximation Ŷ ~ Y. Reaching this objective suppose finding of the expression of the f function and of the values of a1, ..., am parameters. Under assumption of agreement between observation and model the...

The methods measuring the departure between observation and the model were reviewed. The following statistics were applied on two experimental data sets: ChiSquared, Kolmogorov-Smirnov, Anderson-Darling, Wilks-Shapiro, and Jarque-Bera. Both investigated sets proved not to be normal distributed. The Grubbs’ test identified one outlier and after its removal the normality of the set of 205 chemica...

We introduce a new approach to distribution fitting, called Decision on Beliefs (DOB). The objective is to identify the probability distribution function (PDF) of a random variable X with the greatest possible confidence. It is known that f X is a member of = { , , }. 1 m S f L f To reach this goal and select X f from this set, we utilize stochastic dynamic programming and formulate this proble...
